1,2-Propanediol, 3-amino-, (2R)-: A Deep Dive into Its Science, Uses, and Future

Historical Development

In the timeline of fine and specialty chemicals, 1,2-Propanediol, 3-amino-, (2R)- holds an interesting place. Chemists first synthesized and described its core structure decades ago through studies into amino alcohols with potential use in pharmaceuticals and synthesis. During the surge of organocatalysis and chiral auxiliary research in the late 20th century, curiosity around chiral 3-amino-1,2-propanediols gained ground. Manufacturing chemistry carried it further, looking for cleaner, more efficient routes as green chemistry principles crept into industrial policies. Papers in synthetic organic journals followed as researchers uncovered straightforward enantioselective routes, using both enzymatic and chemical catalysis. My background in academic chemistry reminds me that nearly every legacy text on amino alcohols tips its hat to this compound or its close cousins; the field has leaned on these building blocks for asymmetric synthesis for decades.

Product Overview

Recognized for its role as both a chiral building block and an intermediate, (2R)-1,2-Propanediol, 3-amino- serves far more than one purpose in the lab. It often comes as a colorless to pale yellow viscous liquid, with a faint but characteristic odor. Pharmachemical firms usually supply this reagent at a high enantiomeric purity, which proves absolutely essential for making stereospecific drugs or catalysts. Its commercial variations differ in grade, including research-grade, pharma-grade, and for technical synthetic applications.

Physical & Chemical Properties

At room temperature, this amino-diol presents as a syrupy substance, soluble in water and most polar organic solvents. Its boiling point often sits well above 200°C at atmospheric pressure, and its melting point, if the sample is pure enough to crystallize, lands well below room temp. Density typically measures around 1.1 g/cm³. As a molecule sporting both amine and alcohol functional groups, this creates opportunities for hydrogen bonding, reactivity with electrophiles, and use in protective group strategies in synthesis. Chemists note its stability under mild acidic or basic conditions, though prolonged strong acid or oxidative conditions can split or racemize the amino group.

Technical Specifications & Labeling

Labels on product containers almost always highlight stereochemistry, purity, and intended use—crucial for chemists who need reliable, reproducible results. Most bottles come marked with the enantiomeric excess (ee), actual content in percent, relevant hazard pictograms in line with GHS/CLP, and CAS numbers. Additional technical spec sheets include details on water content, residual solvents, trace metals, and sometimes even origins of raw materials, answering demands for responsible sourcing and regulatory compliance. In regulated industries, the difference between a 98% pure bulk product and a 99.5% pharma-grade makes all the difference—failure in labeling accuracy can throw entire batches off course in drug synthesis.

Preparation Method

Industrial preparation hinges on chiral resolution or asymmetric synthesis. Early processes relied on enzymatic resolution from racemates, essentially leveraging biological catalysts like transaminase or hydrolase enzymes to chew through unwanted stereoisomers. Later, organic chemists exploited asymmetric catalytic hydrogenation of precursor molecules, or induced stereoselectivity by chiral auxiliaries and catalysts. Some companies use raw materials sourced from fermentation processes, integrating renewable feedstocks—part of an industry-wide move to lower carbon impact. In smaller labs, synthesis might begin from L-glyceraldehyde, followed by reductive amination, protecting group manipulations, and careful purification to achieve the all-important (2R)-configuration.

Chemical Reactions & Modifications

This compound’s chemical life revolves around both its amine and diol features. The alcohol groups can undergo classic etherification, esterification, and oxidation, yielding a spread of derivatives useful for backbone modifications in organic synthesis. The primary amine opens doors for amidation, reductive alkylation, and even urea or carbamate formation, all critical steps in peptidomimetic and medicinal chemistry. Chemists tweak its properties through acylation or silylation, protecting either the amine or hydroxyl moieties, navigating multi-step syntheses without unwanted side-reactions. Reactions with activated carboxylic acids or anhydrides produce chiral amides, frequently found in pharmaceutical research targeting enzyme inhibitors and receptor modulators.

Synonyms & Product Names

Product listings typically cite synonyms like (2R)-3-Amino-1,2-propanediol, L-Threoninol, or (R)-3-Amino-1,2-propanediol. Some catalogues reference specific names for derivatives, especially if protected or substituted at the hydroxyl or amino site. Pharmacopeial monographs, where relevant, fix the chemical identity precisely to ensure consistent use across research, development, and therapeutic production.

Safety & Operational Standards

Safety profiles matter as much as chemical performance—one slip in the lab can reverse years of careful work. Most reputable suppliers provide detailed SDS with clear instructions on handling, personal protective equipment, ventilation needs, and spill response. While acute toxicity lags behind more potent amines, risks remain: eye and skin irritation can occur with contact, and vapors pose some respiratory hazard in poorly ventilated spaces. Standard lab practice recommends gloves, goggles, and—if heating or reacting at scale—a fume hood. Waste management guidelines stress neutralization before disposal, as small volumes of aqueous solutions can easily find their way into water streams if not properly treated.

Application Area

The lion’s share of use occurs in pharmaceutical synthesis, where this chiral amino alcohol builds scaffolds for drug candidates targeting viral, bacterial, and metabolic disorders. Medicinal chemists value it for the chiral center, offering rapid access to libraries of analogues with defined stereochemistry. Beyond pharma, fine chemical companies rely on it for asymmetric catalysis, turning simple substrates into valuable chiral intermediates in few operational steps. Research into advanced materials and biochemistry sometimes finds ways to anchor 1,2-propanediol, 3-amino- units onto polymers or use them for site-specific protein modifications. Having worked in a contract research environment, I’ve seen it used often in combinatorial chemistry platforms as well.

Research & Development

Recent R&D invests heavily in greener or biocatalytic routes for this and similar compounds, cutting out noxious solvents and minimizing metal waste. Consortia between academia and industry push for new enzymes that handle increasingly challenging substrates, often beating traditional chiral catalysts for selectivity and efficiency. Advanced instrumentation lets chemists probe intermediate steps and untangle reaction networks far faster than before, so the range of derivatives possible with this backbone continues to expand rapidly. Leading pharmaceutical firms partner with process chemists early in the development timeline, knowing that the method for producing intermediates like (2R)-1,2-propanediol, 3-amino-, can shape not just R&D yields but also safety, cost, and regulatory outcomes.

Toxicity Research

Scientists have not ignored its biological risks. Animal studies show modest oral and dermal toxicity; exposure limits aim to curb risk of sensitization or irritation, particularly with repeated handling. Regulatory agencies and safety boards keep a close eye on chronic studies; so far, (2R)-3-amino-1,2-propanediol doesn’t show alarming bioaccumulation or overt mutagenicity at laboratory-relevant doses, yet prudent risk management in industrial settings keeps exposure levels low. I’ve shared lab space with toxicologists who always flagged amino alcohols as materials to be archived, tracked, and documented as research moves from bench-scale to pilot or production.

Future Prospects

Progress in chiral chemistry and green processes forecast a bright future for chiral amino diols. Drug makers keep searching for more efficient chiral reagents which enable shorter, less wasteful synthetic routes. Biocatalysis looks strong as new enzyme platforms make single-step access to key intermediates plausible, even from unconventional feedstocks. Growing concern about environmental impact brings closer scrutiny to every intermediate and processing aid, setting off a wave of innovation for safer, cleaner alternatives. Next-gen materials science may see its role grow, too, as demand rises for bio-based polymer blocks and site-specific drug delivery units. Continued research in toxicology and safe-handling approaches should keep users and communities protected, answering both regulatory and ethical expectations as this compound moves into more hands worldwide.



What is the chemical structure of 1 2-Propanediol 3-amino- (2R)-?

Looking at the Skeleton of This Compound

When you hear “1,2-propanediol, 3-amino-, (2R)-,” chemists probably get excited seeing a backbone that includes three carbons, two alcohol groups, and an amino group. This molecule maps out as a derivative of propanediol with a twist—on the second carbon, the spatial configuration matters. The (2R)- symbol means you’re looking at a specific mirror-image form, not a random blend. Why worry about handedness in molecules? Enzymes and receptors in our bodies, and in most living things, react very differently to each version. Take thalidomide’s history as a painful example: one mirror image helped with morning sickness, the other led to tragic birth defects. Chirality isn’t just a technicality—it changes biology in real ways.

Drawing the Chemical Map

This molecule, also known as (R)-3-aminopropane-1,2-diol, lines up like this: the first and second carbons hold hydroxyl (–OH) groups, and the third carbon hosts an amino (–NH2) group. Written out, you get NH2–CH2–CHOH–CH2OH, with the –OH groups on the first and second carbons and the –NH2 tagging along at the end.

You probably won't spot this compound on store shelves, but it plays a role in research and synthesis. It can pop up while building peptidomimetics, crafting some antibiotics, or exploring how proteins or enzymes recognize specific molecules. This structure gives scientists hooks for further manipulations, adding or swapping groups, or stringing together more complex molecules.

Why the Structure Matters in Practice

It’s easy to take for granted how small tweaks like moving an amino group or changing the chiral center ripple through function. I used to work on a project refining enzyme inhibitors, and swapping just a single group from one spot to another flipped activity from strong binding to zero. Even with compounds as basic as this one, structure shapes how it dissolves, bonds, or participates in reactions. 1,2-Propanediol, 3-amino-, (2R)-, by having both hydroxyl and amino groups, opens doors for hydrogen bonding and new pathways in synthetic chemistry.

You can also see its relatives used in medicines. Many drugs are crafted from molecules with multiple –OH and –NH2 groups because these help anchor them to biological targets. A well-placed amino group turns a bland base into something pharmacologically powerful. A change in chirality can alter solubility, bioavailability, how quickly the liver chews it up, or what tissues it reaches in the body. Drugs and biochemicals with poor solubility or unpredictable absorption don’t always make it to market. This structure, packed with functional groups, can be a starting point for better water solubility and easier metabolism tracking.

Finding Solutions from Structure Knowledge

Chemists face constant pressure to improve existing molecules for better safety, effectiveness, or cost. Knowing the exact layout and behavior of something like 1,2-propanediol, 3-amino-, (2R)- gives a roadmap. Modeling can predict where the molecule will interact and help avoid dangerous side effects or allergies. If your manufacturing process throws off the ratio of mirror-image forms, it’s not just a purity issue—one type may be inactive or, worse, unsafe.

Getting a handle on these details means fewer stumbles in drug development or research. Quality control, precise labeling, and robust synthesis routes all depend on knowing what’s really in the flask. Every time molecular structure translates into a safer medicine or a more useful ingredient, it shows why even a simple molecule like this deserves a closer look.

Is 1 2-Propanediol 3-amino- (2R)- safe to handle and what are its safety precautions?

The Realities of Handling 1 2-Propanediol 3-amino- (2R)-

Anyone who has worked in a lab or spent time in industrial settings knows chemicals come with different risks. I’ve handled dozens of odd-sounding compounds over the years, and each required a clear protocol. 1 2-Propanediol 3-amino- (2R)-, with its unique structure, falls into the category of organic chemicals where treating it lightly simply isn’t an option. Direct skin or eye contact with something like this can cause irritation, and accidental inhalation brings its own problems. Some people build confidence over time, but that’s often when slip-ups happen. One distracted moment or a forgotten pair of gloves, and you start understanding why those safety sheets matter.

Why Safety Sheets and Training Matter

Let’s get one fact clear: safety data sheets (SDS) exist for good reason. They hold the fine print—health effects, fire risks, what to do in an emergency. Skipping this step turns what should be a routine process into a guessing game. I recall working with an amine compound years back; my supervisor stopped a rushed colleague from pouring it without goggles. That colleague avoided a trip to the clinic because the rules were clear and people kept each other accountable. Even mildly toxic chemicals like 1 2-Propanediol 3-amino- (2R)- aren’t forgiving if they’re mishandled.

Personal Protective Equipment is Not Just for Show

Goggles, gloves, lab coats—they’re the last line of defense. Nitrile gloves hold up against most organic compounds, though not forever. Double gloves help with splashes. I keep a pair of safety goggles on my workbench. Chemical-resistant aprons work best when mixing larger amounts. Miss one step, and you end up needing eyewash stations or emergency showers, which are designed for serious spills or accidental dousing. Over the years, everyone I know picks up the habit of pre-checking safety gear the same way they clear a stove before cooking; skipping the basics rarely ends well.

Ventilation Makes a Difference

Organic amines, including this one, can produce irritating vapors. Fume hoods aren’t luxury items—they pull airborne hazards away from noses and lungs. At my old research lab, nobody pipetted these substances on the bench, not after someone else complained of headaches one day. Ventilation systems aren’t something you notice until they quit; a single non-functioning exhaust can turn a safe room into an uncomfortable—and unsafe—space. Paying attention to airflow and regular system checks should be part of every workplace’s routine.

Storing and Transporting Safely

Storing chemicals without crowding shelves or mixing incompatible groups avoids surprise reactions. 1 2-Propanediol 3-amino- (2R)- needs a cool, dry spot, and tightly closed containers. Clear labeling saves time and nerves, especially during a busy day. Transporting involves carrying small quantities—usually in secondary containment—so even if a bottle drops, there’s no major mess. It sounds dull, but the alternative means emergencies that interrupt everyone’s work.

Training Means Fewer Accidents

New staff learn correct handling by watching experienced colleagues and through hands-on drills. Sharing stories from the trenches sticks more than reading regulations. In my experience, regular safety refreshers don’t just meet compliance—they keep the culture sharp. Even those who "already know everything" pick up something new. Chemical safety is written into the DNA of any successful lab or factory.

Catching Problems Early

Noticing the first sign of a spill or feeling a symptom—cough, burning sensation, dizziness—should push people to speak up fast. Treatments are most effective soon after exposure. Incident log books serve as reminders, highlighting problem areas and driving slow but steady improvements across teams. I’ve watched experienced crews catch leaks with their noses or eyes before alarms even sound. This vigilance makes a difference and cuts down on emergencies.

Conclusion: Respect the Process

Trusting the process and sticking to proven protocols isn’t about slowing progress—it’s about keeping people healthy. The safest labs and factories earn that record one careful day at a time. The best solution: Listen, learn, and never skip the steps that seem obvious.

What is the CAS number or molecular formula for 1 2-Propanediol 3-amino- (2R)-?

Chemistry Details Aren’t Just for Scientists

Many folks outside the lab might glance over a compound name like 1,2-Propanediol 3-amino-(2R)- and wonder why anyone cares about the fine print—such as the CAS number or molecular formula. Yet in my years around supply chains and regulatory work, missing or mistaking these details has real-world consequences. Imagine ordering the wrong chemical, or failing a safety inspection because a database can't match your product’s documentation. Clarity isn’t just a science concern—it keeps systems running and people safe.

CAS Numbers Prevent Costly Misunderstandings

A CAS number, short for Chemical Abstracts Service number, acts as a unique fingerprint for chemical substances. Each number points to one and only one specific chemical—nothing else. 1,2-Propanediol 3-amino-(2R)- carries the CAS number 4779-56-2. Without it, paperwork turns into educated guessing, especially when products shift between languages or different naming habits.

Folks in the pharmaceutical industry, for example, rely on CAS numbers to comply with regulations—no regulator gives much weight to “sort of right.” I’ve witnessed manufacturing floor delays all because someone couldn’t find a reliable number—or worse, used a similar-sounding name. That slows everything down, hikes up costs, and sometimes leads to wasted batches.

Why the Molecular Formula is More Than a List of Letters

A molecular formula—here, C3H9NO2—gives more than a tidy summary. It defines what you’re really getting. Many isomers can look the same to a hurried clerk, but not on paper. Mistakes in chemistry often trace back to skipped scrutiny at this level. I’ve met junior engineers who trusted a supplier’s generic label only to find their products throwing off quality control checks later. Those letters and numbers aren’t just scientific trivia; they’re a straightforward way to verify and trace what actually sits in your drum or bottle.

Stopping Errors Before They Start

Chemical safety plans and compliance programs depend on accurate reference numbers and formulas. Too many companies think training stops at safe handling, forgetting that accurate records form the backbone of any chemical operation. Simple steps—like double-checking CAS numbers and formulas at every step—consistently pay off. I’ve worked with colleagues who stamp each delivery slip with the CAS number and formula before signing off. Not glamorous, but these habits produce far fewer mishaps down the road.

Suppliers and distributors working across borders see even bigger benefits. A CAS number maintains meaning no matter which country or language the shipment crosses into. That’s key for global markets, where a slight error in translation can spell disaster or legal trouble.

Supporting Science—And Common Sense

Rooting supply chains and safety efforts in solid facts grows credibility and builds trust with auditors, partners, and clients. Transparency, traceability, and accuracy become habits, not hurdles. As someone who’s traced down paperwork through a half-dozen departments just to pin down a chemical’s true identity, I appreciate the straightforwardness a CAS number and molecular formula provide. The details may feel tedious, but those who pay attention avoid many headaches.

How should 1 2-Propanediol 3-amino- (2R)- be stored and transported?

Real-World Storage Tactics

1 2-Propanediol 3-amino- (2R)-, though its name sounds like a chemical straight out of science fiction, plays a real part in research labs and chemical supply chains. Anyone who’s opened a bottle of a sensitive compound knows the smallest slip-up can spoil both the product and the experiment. This chemical falls in that camp. I’ve worked with many compounds where temperature swings or bad seals got the better of the sample, and nothing stings quite like wasted material, especially when budgets are tight.

Storage should always start with a well-ventilated space away from direct sunlight. Heat and light break down many organics. Keep it in a cool, dry place—cold rooms or climate-controlled cabinets work best. Moisture makes trouble; extra water can wreck purity and leave you guessing what exactly’s in your bottle. Sealing every container tight keeps out atmospheric water and limits oxidation, which can lead to dangerous byproducts or a simple loss in quality. Glass containers with screw tops and rubber or PTFE seals do the job better than plastic. Ships in glass for a reason.

Labels should show the full name, concentration if it’s a solution, hazard icons, and an up-to-date date of receipt. I’ve watched the fallout from unlabeled bottles—nobody wins when someone gets exposed or wastes time contacting suppliers to identify mystery samples. Good records help when things go sideways and you need to track a problem back to a specific lot.

Transport That Prevents Trouble

Moving chemicals, even for a short hop between labs, brings reminders about spills and breakage. For 1 2-Propanediol 3-amino- (2R)-, using secure secondary containment—like plastic pails or padded carriers—gives peace of mind. Double-layer packaging, especially for risky or valuable compounds, is standard among the best lab teams. If containers leak in transit, a good secondary layer keeps the problem from spreading.

Shipping companies with documented experience in hazardous or sensitive materials bring down risk. Pick a carrier who won’t let your package sit in the sun or freeze up in a warehouse. Temperature data loggers can record the trip and settle disputes if quality drops. It isn’t paranoia—it’s about not losing a week’s work. Regulations from groups like IATA or OSHA spell out the details, but at the end of the day, a bit of vigilance beats paperwork after something bursts open.

Why Smart Handling Matters

Lost or degraded material brings costs that go far beyond dollars. Research gets delayed, trust erodes, and lab morale tanks. On top of that, some chemicals—propanediol derivatives among them—can pose health hazards. I’ve seen skin irritation and breathing problems from careless transfer or a poor glove choice. Take the right precautions and the risk plummets. Goggles, gloves, and a fume hood add layers of safety no one regrets.

Steps to Sharpen Your Approach

Think ahead. Check your stocks weekly. Make sure every bottle stays sealed unless you’re using it. Invest in clearly marked secondary containment. Bring staff into the loop with briefings and reminders—people remember stories about what can go wrong more than they remember pages from a binder. Choose the right suppliers and logistics partners, and insist on temp-tracking for any shipment during extreme weather.

In the end, storing and moving 1 2-Propanediol 3-amino- (2R)- safely means more science, fewer headaches, and a tighter operation. That’s what counts.
