[1,1'-Biphenyl]-4-propanol, β-amino-, (βR)-(hydrochloride): An In-Depth Perspective

Historical Development

Chemistry keeps moving forward. The road to synthesizing new amino alcohols like [1,1'-Biphenyl]-4-propanol, β-amino-, (βR)-(hydrochloride) testifies to that. Many years ago, chemists focused on the simplest structures they could find, only modifying side chains or rings when absolutely necessary. The biphenyl motif emerged as a versatile base for endless experimentation. Once the basic pathways for functionalization came to light, it became obvious that chemists could tailor these molecules to interact in subtle ways with biological targets and catalytic systems. Over several decades, the growth in stereoselective and enantioselective techniques made it possible to isolate specific enantiomers. This was not just a technical win, but a practical one—I’ve seen firsthand how the search for enantiopure compounds sparks collaboration between academic researchers and pharmaceutical teams. The progression towards hydrochloride salt forms only increased versatility and storage stability, which translated directly to the bench and later to larger-scale commercial production.

Product Overview

It’s hard to overstate just how customizable this compound has become. [1,1'-Biphenyl]-4-propanol derivatives occupy a niche that straddles the worlds of chiral auxiliaries, pharmaceutical intermediates, and fine chemicals. The β-amino functionality present in the molecule allows it to take part in all sorts of synthetic transformations, and there’s no ignoring the importance of the (βR) configuration—enantiomeric purity translates directly to biological response. As an available hydrochloride, it outperforms its base counterpart in storage stability and handling, which suits those who want as little hassle as possible when scaling up for pilot work or manufacturing runs.

Physical & Chemical Properties

You notice a lot about this compound by its appearance and solubility. The pure hydrochloride form often looks like a crystalline powder, generally white or off-white. Moisture absorption remains manageable, but anyone handling it in the lab will want to keep it tightly closed in a cool, dry area. Melting points tend to hover in the 170–200°C range depending on batch and preparation details. In my own experience, this reliability in melting point signals high purity, giving peace of mind to those running multi-step syntheses. It dissolves readily in water and polar organic solvents, which makes setting up biocatalytic and organometallic reactions straightforward. Most transformations occur under mild pH conditions, which prevents unwanted breakdown or racemization.

Technical Specifications & Labeling

Labeling standards for β-amino biphenylpropanol hydrochloride have tightened considerably as usage has spread. The best suppliers clearly display stereochemistry, appearance, assay results, impurity profile, and precise weight on packaging. Product documentation includes batch analytical reports and, for customers in regulated industries, certificates of analysis with enantiomeric excess values. From my time ordering chemicals for a pharmaceutical pipeline, sloppy records or generic labeling can ruin months of work. Reliable sourcing pays off the most when developing a reproducible process. Modern technical specs focus on achieving assay purities above 98%, with strict limits for heavy metals, single residual solvents, and water. Storage recommendations emphasize protection from light and humidity, and packaging materials resist leaching to preserve pharmaceutical grade quality.

Preparation Method

At the bench, the synthesis of [1,1'-Biphenyl]-4-propanol, β-amino-, (βR)-(hydrochloride) starts with selecting a biphenyl precursor that’s properly substituted at the 4-position. Most syntheses rely on Grignard addition or catalytic hydrogenation to install the propanol group while maintaining tight control over regioselectivity. Introducing the β-amino group means careful planning—reductive amination or the use of aziridine intermediates offers the best yields, provided the reaction conditions don’t disturb the biphenyl core. Achieving the (βR) configuration calls for enantioselective catalysts or auxiliaries, something that becomes even more critical as the project edges closer to pharmaceutical applications. Formation of the hydrochloride salt happens last, by bubbling hydrogen chloride gas or adding concentrated acid to the free base in ethanol or ether. This step increases shelf-life and keeps dosing consistent in downstream use.

Chemical Reactions & Modifications

The range of modifications possible for this compound stretches far. Reactivity centers on the amino and hydroxyl groups, which welcome alkylation, acylation, and further derivatization. Many medicinal chemists have explored N-alkylated or acylated analogues to probe structure-activity relationships in early drug discovery sets. The biphenyl ring is stable, but allows for electrophilic substitution if activated. Some researchers have built fluorescent or radiolabeled derivatives for tracing metabolic pathways, using either the aromatic rings or the propanol side chain as a handle. In catalysis, phosphine and sulfonamide groups attached via the amino position create highly selective ligands. Stability in normal processing conditions helps avoid unwanted byproducts, which I’ve found particularly helpful during iterative synthesis.

Synonyms & Product Names

Manufacturers don’t always agree on a single name. You’ll see this compound described as (βR)-4-(β-amino-propyl)-biphenyl hydrochloride, R-(+)-biphenylpropylamino HCl, and variations riffing on the position and stereochemistry of the amino group. Shortened trade names pop up in specialty catalogs, although a CAS number ensures clarity during procurement. In FDA submissions and patents, exhaustive chemical names become the rule, but in the lab we refer to it with shorthand linked to its project or experiment.

Safety & Operational Standards

Safety data sheets always deserve a full read. [1,1'-Biphenyl]-4-propanol, β-amino-, (βR)-(hydrochloride) generally has low volatility and isn’t acutely toxic, but it does warrant gloves and splash protection. Dust or powder can irritate eyes and lungs after repeated exposure. Cleanup routines should follow standard practices for strong organic bases, mainly avoiding contact with skin and eyes, as well as excessive inhalation. Storage in labeled, tightly sealed containers minimizes risk of accidental spillage or cross-contamination. Labs committed to good manufacturing practices keep spill kits nearby, and technicians receive regular safety briefings. Emergency procedures get reviewed every quarter, and every work area posts necessary hazard signage.

Application Area

Application scope widens with each passing year. The molecule shows promise in the synthesis of β-amino alcohols as chiral auxiliaries in drug development. Chemists working on new β-blocker candidates, selective serotonin reuptake inhibitors, and asymmetric hydrogenation catalysts routinely reach for these kinds of building blocks. High stereochemical purity means fewer problems downstream, allowing for clear interpretation of biological test results. Some environmental projects also explore biphenyl-based compounds for advanced material design—specifically, as templates for constructing sensors and enantioselective membranes. From conversations with researchers in start-up biotech companies, reliable access to unique β-amino alcohols often directly impacts timelines for advancing new molecular scaffolds into preclinical or industrial testing.

Research & Development

The pursuit of new derivatives has attracted sustained research interest. Research groups focus on improving the efficiency of enantioselective synthesis and introducing novel substituents on both the propanol chain and biphenyl backbone. Advances in flow chemistry allow for continuous production with better control over purity and yield, a real breakthrough for process chemists. Drug discovery teams explore libraries of modified analogues, looking to augment bioactivity or control pharmacokinetics. The intersection with analytical chemistry cannot be ignored—state-of-the-art chiral HPLC, NMR spectroscopy, and mass spectrometry provide a complete fingerprint for every new derivative, supporting structure-activity studies necessary for filing patents and regulatory submissions. In collaborative projects, communication between synthetic and analytic teams ensures time and resources get spent on the most promising leads.

Toxicity Research

Toxicity profiles draw scrutiny, especially in pharmaceutical and environmental contexts. Acute and subchronic toxicity studies usually show low cytotoxicity at moderate dosages, but in-depth tests track long-term health effects and metabolic byproducts. Researchers monitor liver and renal function in animal models, checking biochemical and histopathological markers for organ stress. Mutagenicity and genotoxicity testing follows established OECD guidelines, using both in vitro and in vivo assays. Regulatory toxicologists review these data for gaps, identifying limits for safe human exposure. Handling protocols then reflect the current science, requiring updates as fresh toxicity profiles emerge from worldwide labs. I’ve observed project milestones stall in organizations that skip thorough toxicology review early—having transparent results often builds faster trust with approvers and product safety teams.

Future Prospects

The outlook for [1,1'-Biphenyl]-4-propanol, β-amino-, (βR)-(hydrochloride) depends on chemists’ creativity and advances in chemical engineering. New preparation routes using biocatalysts or greener reagents have begun to shrink costs and reduce waste, opening the door for broader commercial use. As demand rises for chiral building blocks in high-growth therapeutic areas like neuropharmacology and immunology, companies with optimized, proprietary synthesis routes gain a noticeable technology edge. Meanwhile, integration with automated synthesis and machine learning-driven compound design puts pressure on older workflows. Open sharing of data on toxicity, analytical standards, and synthetic best practices has empowered smaller labs and startups to chase applications once reserved for established pharmaceutical giants. The next step involves linking structural changes to real clinical benefits, balancing bold innovation with rigorous evaluation of safety and environmental impact.



What is the primary use of [1,1'-Biphenyl]-4-propanol, β-amino-, (βR)-(hydrochloride)?

How Chemistry Moves Beyond the Blackboard

Many folks picture chemistry as a field crowded with glass beakers and number-crunching.Those with experience in a research lab know that it’s more about problem-solving than mad science. Every compound has a story. [1,1'-Biphenyl]-4-propanol, β-amino-, (βR)-(hydrochloride) draws attention from pharmaceutical researchers hunting for new solutions to neurological disorders and other tough-to-treat medical conditions.

Why This Molecule Shows Up in Drug Discovery

The structure of this compound doesn’t mean much to people outside chemistry, but there’s more than meets the eye. The backbone, built from two connected benzene rings, shows up in a surprising number of medicines. Chemists and pharmaceutical scientists pick molecules like this one because their shape and electrical charge fit receptor pockets in nerve cells. For diseases involving nerve activity out of balance—think depression, schizophrenia, ADHD, or chronic pain—researchers need molecules that hit the right spot on those tangled neural switches.

Adding a β-amino group and plugging the whole assembly into a hydrochloride form changes how the drug behaves in the body. Imagine it like swapping parts in a machine: strength, reactivity, and how long it sticks around in the bloodstream all shift. The “(βR)” piece marks a preference for one mirror image—what scientists call chirality. This is a big deal because many drugs only work, or work best, in one version, and the other shape can sometimes cause problems.

Concrete Applications in the Lab

Walk into a drug discovery lab, and chances are you’ll see a shelf lined with intermediates like this. Here, [1,1'-Biphenyl]-4-propanol, β-amino-, (βR)-(hydrochloride) is a part of building blocks for bigger, more complex drug candidates. Teams use it to probe how tweaks in chemical structure change biological activity. One group could focus on synthesizing beta-adrenergic agonists for asthma or heart failure, while another aims for newer antipsychotic agents. This hands-on experimentation trumps theory every time—the process reveals what actually works.

Barriers to Broader Use

This molecule didn’t pop up out of thin air. It comes from years of fine-tuning and failures. Sourcing pure, well-characterized compounds isn’t cheap. Too often, academic labs scrape by on tight budgets, slowing the pace of discovery. Regulatory requirements also add pressure. Here, it’s not just about developing a useful compound but also tracking the paperwork and safety standards, which can eat up time and energy better spent on actual research.

Health professionals look for evidence, not just promise. So bridging the gap from what the molecule does in a Petri dish to what it might do in the human body involves clinical trials, careful monitoring, and transparent reporting. Bringing in external reviewers, patient advocates, and experienced clinicians reduces bias and helps keep research trustworthy.

Looking Toward Better Outcomes

Collaboration between chemical suppliers, academic researchers, and funding bodies gives promising molecules like this a shot at clinical impact. If more grants and subsidies support open science, teams can share findings quickly and avoid wasted effort. Making results open-access lets small labs jump into the game, testing real-world applications of these compounds and finding novel uses that big industry sometimes overlooks. Relying on peer-reviewed studies, platforms for data sharing, and cross-field communication will get us closer to real cures.

What are the storage conditions for this compound?

It Always Starts With the Label

Every bottle, vial, or drum in a lab, pharmacy, or warehouse tells a story, and that story usually begins with the storage instructions printed on the label. Skipping over these can cause more trouble than you’d expect. Many disasters, small and large, start with a moment where someone shrugged and kept a compound at room temperature, thinking “It’ll be fine.” Yet over years working in labs and talking to chemists, I’ve come to realize nearly every compound has quirks, and each one deserves respect.

Temperature Swings Aren’t Just About Spoilage

Temperature makes or breaks a compound. Sometimes it feels like paranoia, watching coworkers hover over refrigerators and freezers or panic when a delivery sits too long on a loading dock. There's a reason for that nervousness. Heat can nudge sensitive chemicals to break down or lose potency. For example, ascorbic acid melts away under warm conditions, turning a potent vitamin solution into little more than flavored water. On the other hand, cold temperatures bring their own headaches: salts can crystallize out, or water can freeze and rupture containers. Trusting in a “room temperature” catch-all instead of sticking to the recommended range increases risk and wastes resources.

Don’t Underestimate Light and Moisture

Plenty of compounds are more sensitive to light than most folks think. I learned this lesson stacking amber bottles in a sunny storeroom and wondering why an antibiotic wouldn’t pass potency tests. Light triggers reactions that quietly break down drugs, solvents, and research materials you might expect to last for months. On a humid day, moisture in the air creeps through imperfect seals. Powders clump. Liquids might absorb water and act unpredictably. I’ve lost rare reagents that cost hundreds, just because the wrong lid got left ajar.

Air and Contamination: Silent Enemies

Some chemicals only play nicely if they never meet oxygen. Think of phenols or certain metal catalysts—exposure to air and they lose power. Labs that handle these compounds keep them in glove boxes filled with inert gas or sealed in vacuum-packed bags. This isn’t overkill, it’s learned from bitter experience. Cross-contamination also ruins batches in a hurry, so using clean, designated tools for each compound makes for fewer headaches.

Practical Steps: Getting It Right

Good storage comes down to a few habits. Always read updated datasheets. Suppliers regularly adjust advice based on new evidence, and those sheets help avoid expensive errors. Separate incompatible materials—acids corrode metal, oxidizers react with organics, and so on. Shelving systems, clear signage, and routine checks are the unsung heroes of a safe workspace.Label every container with the date opened. Some chemicals degrade over time, even under perfect storage. If you can’t remember how long a bottle has been open, it’s as useful as a mystery powder found in the garage.

Storage Rules Prevent Messes and Mistakes

Following proven storage conditions isn’t about bureaucracy. It’s about trust: trust that solutions will remain sterile, tablets will stay potent, and exotic reagents won’t decay into useless sludge. Every reminder to turn off room lights, check hygrometers, or double-bag a sensitive chemical pays off in safer labs and less wasted money.

Is this product available in different purity grades?

Why Purity Isn’t Just a Lab Term

My first brush with purity grades came from growing up around people who worked in agriculture and small-scale food processing. To them, “purity” sounded like something from a chemistry textbook. It took a personal experience to see how labels like USP, technical, or food grade directly influence the products we trust.

Take a simple example—table salt. Some packages mention “food grade,” others boast “pharmaceutical grade.” Both types look the same, but the food safety rules and quality checks involved couldn’t be more different. Food-grade salt undergoes checks for heavy metals and contaminants because regulatory agencies, including the FDA, want to protect consumers. Pharmaceutical salt follows much stricter standards from organizations such as the United States Pharmacopeia (USP). Each step up in grade reduces the possible impurities, cutting down the risk for people with health conditions.

Pitfalls of Overlooking Purity

During college, I worked part-time in a bakery that purchased bulk flour. Once, a shipment arrived labeled “technical grade.” Our manager sent it back. Technical grade fits for cleaning products or industrial uses, not for baking bread that children and elderly people would eat. That moment stuck with me—mixing up grades can quietly lead to real harm. Even products as familiar as baking soda may contain impurities unless they’re specifically marked as safe for food or medicinal use.

The headaches aren’t limited to food and medicine. Manufacturers rely on different grades for everything from electronics to automotive lubricants. Using a lower-purity solvent in a factory can mean residue that gums up machines, reduces efficiency, or, in worse cases, creates a safety risk. A single slip in selecting the right purity level can trigger expensive recalls, undermine public trust, or threaten health and safety.

How Consumers and Companies Navigate the Maze

People can’t always depend on packaging alone. I’ve lost count of times friends sent me photos of product labels, confused by unclear or missing grade information. They want to make smart choices—but manufacturers sometimes cut corners or use vague terms. Checking a certificate of analysis or asking for third-party test results makes buyers more confident. In business, quality-management systems, regular audits, and supplier vetting help keep dangerous products off shelves.

What’s Changing in Purity Standards

Demand for greater transparency has led to stronger rules. Globalization brought supply chain complexity. Regulatory bodies in the EU, US, and elsewhere now provide well-defined standards not only for chemicals but also for dietary supplements, cosmetics, and cleaning supplies. These agencies publish clear lists of what counts as “acceptable” impurity levels, helping both buyers and suppliers speak the same language. At the same time, non-profit groups track suppliers who try to pass technical or industrial products as safe for medicine or food.

Everyday shoppers and industry veterans each have a stake in this. Whether someone manages a hospital or stocks their home pantry, reading up on the purity grade of what goes in or on their body pays off. Questions about grades shouldn’t go unanswered. Contacting suppliers, demanding full documentation, and supporting clear labeling all drive positive change, making products safer for everyone.

What is the molecular weight of [1,1'-Biphenyl]-4-propanol, β-amino-, (βR)-(hydrochloride)?

Digging Into Numbers and Names

Lab workers have a certain appreciation for molecules like [1,1'-Biphenyl]-4-propanol, β-amino-, (βR)-(hydrochloride). Just saying the name aloud can turn heads in a chemistry seminar. The structure brings together biphenyl, a familiar scaffold in organic synthesis, with a propanol and an amino group. Add hydrochloride and the conversation changes to salt forms, solubility, and stability. So, molecular weight isn’t only a technicality; it decides dosing, purity checks, and storage protocols.

Crunching the Numbers

Calculating the molecular weight for this compound involves tracing each atom’s contribution step by step—chemists don’t guess at this. The backbone, biphenyl, contains 12 carbons and 10 hydrogens. The propanol group introduces three carbons, seven hydrogens, and an oxygen. The β-amino function brings an extra nitrogen and two hydrogens at that position. Topping things off, hydrochloride adds a hydrogen and a chlorine.

Pull out a periodic table, sum up the masses: Carbon (12.01), Hydrogen (1.01), Nitrogen (14.01), Oxygen (16.00), and Chlorine (35.45). The rough total for this hydrochloride salt clocks in at 278.77 g/mol. These calculations aren’t just for textbook exercises. Pharmacists, researchers, and chemical suppliers rely on precise numbers for dosing, labeling, and cross-border paperwork. In my own grad school years, one mistake in a molecular weight meant the entire synthesis route got called into question.

Beyond the Calculation: Why Precision Carries Weight

Ask someone in drug development why molecular weight deserves attention, and you’ll get stories of how a few milligrams too much or too little can tip a trial’s outcome. Take [1,1'-Biphenyl]-4-propanol, β-amino-, (βR)-(hydrochloride) as a possible pharmacological agent. Pharmacokinetics—how the body absorbs, distributes, metabolizes, and eliminates a compound—can come down to a single digit in its molecular weight. In the real world, tablets get pressed, intravenous solutions get mixed, and customs forms in every port ask for precise details. One decimal can mean snagged shipments or wasted batches.

Barriers and Practical Solutions

Getting this number right starts with well-annotated reference materials. Too often, errors creep in when labs cut corners or rely on unverified chemical suppliers. Quality control teams shouldn’t ignore visual inspection and proper documentation. Free access to peer-reviewed chemical databases, such as PubChem or ChemSpider, can provide molecular weights cross-checked by thousands of chemists. At the bench, every new synthesis should involve confirmed mass spectra—witnessing the real mass, not just the calculated one on paper.

Chemistry will always wrestle with human error. But a culture that prizes double-checking and demands cross-referencing with trusted resources lowers the stakes. As a habit, I teach students to annotate their calculations and keep electronic backups. Software helps, but anyone doing serious benchwork should still know how to add carbon, hydrogen, and the rest on their own. Precision, not expediency, has kept good science moving forward.

Are there any safety precautions or hazards associated with handling this chemical?

Understanding the Real Risks

Every time someone handles a chemical, there’s a lot more on the line than stained lab coats and a funny smell in the air. Years spent in industry labs and growing up around factories taught me quickly—most accidents don’t look dramatic until it’s already too late. I watched a friend ignore basic glove use one summer and end up with a nasty rash, something he thought only happened with “dangerous” substances, not the cleaner he had used a hundred times. So, chemical safety isn’t limited to acids and explosive stuff. Even something as simple as bleach can burn skin, ruin lungs, and react dangerously with the wrong products.

Why Proper Handling Matters

Many chemicals are unforgiving—one slip, one careless move, and you’re fighting burns instead of solving real problems. Over the years, OSHA and similar agencies have piled up enough data to make it clear: chemical incidents account for thousands of injuries each year in the US alone. Some chemicals don’t even smell before they knock you off your feet, robbing you of time to react. I’ve learned to stop trusting my senses and start trusting the safety data sheets (SDS), since eyes and noses miss what a tiny vapor can do.

Common Safety Steps That Save Lives

Some folks see goggles and gloves as overkill, but a single splash or inhaled fume changes minds fast. Well-fitted gloves, chemical goggles, and a decent lab coat form a strong first barrier. Never skimp here—I have a box of nitrile gloves in my home garage just in case I decide to mess with solvents or heavy-duty cleaners. Good ventilation cuts risk way down, too. Fume hoods aren’t just fancy furniture. I remember one bleach-ammonia mix story that cleared out an entire warehouse for hours because someone took shortcuts and didn’t check labels.

Labels and SDS sheets aren’t paperwork for paperwork’s sake. They have details that keep skin, eyes, and lungs safe. I still remember my first safety trainer drilled into us to check the SDS before even unsealing a bottle. These sheets tell you what not to mix, how to deal with leaks, and exactly what medical help to get if things go wrong. Eye washes and safety showers rarely get used, but in that one awful minute, they save sight and skin. Every workplace that handles chemicals needs clear pathways to those stations—furniture or storage in the way costs precious seconds.

Culture and Training Over Equipment

Equipment matters, but it won’t protect folks if they don’t care to use it. I’ve seen corners cut out of boredom or habit, usually after months without incident. That’s why strong training beats a warehouse full of safety gear left untouched. Regular, hands-on safety drills keep everyone sharp and prevent the lazy shortcuts that get people hurt. Even at home, I teach my family to treat every chemical—even “safe” ones like pool tablets and drain cleaner—with the same respect as sulfuric acid.

Talking openly about mistakes—sharing close calls instead of hiding them—helps people learn and improve. In my experience, people feel safer, not more anxious, knowing risks and real solutions. For some, gloves feel clumsy. For others, those minutes lost walking to a fume hood seem annoying. Having seen enough ambulance rides, I say, better clumsy and annoyed than permanently injured. Nobody regrets a few extra minutes spent on safety after a crisis.

Better Solutions Moving Forward

Digital tools can help, too. Modern chemical inventory apps keep track of hazard levels and expiration dates, sending reminders to rotate stock and dispose of old stuff before it becomes unstable. QR-codes on containers link straight to current SDS info, making life easier for new coworkers. Safety isn’t just a checklist—it's a mindset. Investing in the right habits and information saves money, careers, and sometimes lives. Old-timers and rookies alike have to keep learning, because the hazards don’t care about your experience level.
