2-Amino-2-ethyl-1,3-propanediol first emerged in the chemical catalogs long before digital records tracked every innovation. Chemists in the mid-20th century looked for small, manageable amino alcohols and stumbled onto this one because they needed reliable buffering agents. Lab notes from those eras show interest in creating compounds that balanced low toxicity with decent reactivity. As researchers experimented with amino alcohols, word started to spread about its ease of handling and versatile reactivity.
This compound has gained a reputation in laboratories and manufacturing plants for its straightforward handling and suitability across research and production lines. Its structure—short carbon backbone with an amino group and two hydroxyls—sets it apart from more complex scaffolds, keeping synthesis practical and cost-effective. Companies supply it for buffer preparation, chemical synthesis, and certain specialty coatings, counting on its predictable nature and steady supply chain.
In solid form, 2-Amino-2-ethyl-1,3-propanediol usually appears as a white or slightly off-white crystalline powder, often giving off a faint, characteristic odor. It melts at around 38–41°C, which allows for easy melting without elaborate safety setups. With a boiling point close to 175°C at reduced pressure, it stays stable under regular lab conditions. Solubility in water remains one of its big strengths—dissolving quickly without clumping, so users rarely battle with inconsistent solutions. Its moderate basicity (pKa near 9.5) suits it for buffering applications in biochemical work.
Suppliers list 2-Amino-2-ethyl-1,3-propanediol at purities over 98%, with clear labeling of CAS number 115-70-8. Typical technical sheets set out allowable moisture levels, heavy metal limits, and residual solvent content, which reflect tighter international standards. Shipping containers must indicate "amino alcohol" and advise on personal protective equipment due to mild irritant warnings, especially regarding prolonged skin contact.
Commercial production draws on straightforward organic synthesis, mostly by introducing ethylene oxide to 2-aminopropanol under mildly basic conditions. This method avoids complex conditions or dangerous by-products, making scale-up less hazardous. Plants across Europe and East Asia consistently use catalytic reactors, which cut down on waste and costs without needing extensive purification. Yields often reach 85–90%, letting manufacturers meet steady demand.
The amino and hydroxyl groups on the backbone open the door for a range of reactions. Scientists often exploit its reactivity through acylation, alkylation, or condensation, tailoring it for drugs or specialty chemicals. It interacts predictably with carboxylic acids to form amide linkages, boosting compatibility with polymers or resins. Oxidation reactions modify it in controlled ways for fine chemicals and intermediates. Its structure helps anchor it onto surfaces, which supports work in biomaterials and catalysis.
You may find this compound listed as AEPD, Bis(2-hydroxypropyl)amine, or Monomethyltriethanolamine on product sheets. These names reflect earlier trade conventions or supplier preferences—so checking a chemical registry always helps. Major distributors, such as Sigma, Merck, Fluorochem, and TCI, carry it under at least two names, leading to confusion, especially in cross-border orders.
Even though major safety issues rarely come up, users still need to respect lab protocols. This compound can cause irritation if inhaled or with direct, repeated skin contact. Eye exposure triggers stinging—something any bench chemist dreads. Standard operational standards call for gloves, goggles, and fume hoods during weighing and solution preparation. Ventilation counts just as much here as with more noxious amines, despite its relatively pleasant handling properties. Companies log material safety data not simply for compliance but to keep researchers and operators in top shape.
Biochemists use 2-Amino-2-ethyl-1,3-propanediol most often as a buffer in protein and enzyme assays where you need tight pH control between 7 and 10. Manufacturers appreciate how well it stabilizes pH in water-based paints and surface coatings. In oil fields, formulations containing this chemical help break down drilling fluid emulsions. Chemistry educators adopt it for teaching basic synthesis and analytical chemistry. Further up the value chain, pharmaceutical companies and cosmetic producers opt for it when they need mild chemical bases that do not upset sensitive formulations.
Academic research drives much of the ongoing interest in this amine. Recent studies have looked at its use as a stabilizer in nanoparticle synthesis, where old-school buffers sometimes fail. Several research groups examine its role in modifying hydrogels for wound dressings or sensors, drawing on that reliable combination of chemical compatibility and low toxicity. Papers track its pharmacokinetics and biodegradability, feeding into late-phase pharmaceutical work. Research grants increasingly reward projects that rely on chemicals with a strong safety and sustainability record, and this compound fits that profile well.
Toxicologists have put this compound through the paces, testing acute and chronic effects. Standard oral and dermal exposure tests show low toxicity at moderate levels, though large doses can lead to mild renal or hepatic stress in animal models. No strong evidence links it to mutagenicity or carcinogenicity, based on available studies and regulatory reviews. Chronic low-level exposure still prompts recommendations for basic safety gear in labs and production lines, but most reported cases of adverse effects involve improper storage or spillage. Monitoring breathability and skin exposure in high-throughput plants stands out as an easy step to keep risks in check.
Markets for 2-Amino-2-ethyl-1,3-propanediol look solid, with growth tied to expansion in biotech and green chemistry. As researchers focus on replacing harsher amines, this compound’s mild profile plays in its favor.

Sustainability advocates watch its lifecycle footprint, and companies pivoting toward green certification see long-term value in keeping it on spec and in regular stock.
Ask a seasoned chemist about 2-Amino-2-ethyl-1,3-propanediol, and you’ll probably get an earful about its role in the laboratory. Folks often shorten its name to AEPD, especially when talking about its use as a buffering agent. In my work, I’ve used it during protein purification and enzyme studies. Its steady pH support helps prevent wild swings that could ruin sensitive biological samples. Turning away from the microscope, AEPD reaches into many corners of the chemical world you’d never expect.
Inside pharmaceutical research, AEPD helps medicines keep their shape and effectiveness. Companies build it into drug formulas to stop nasty surprises when pills sit on the shelf. If you’ve taken a medication with a long expiration date, chances are a buffering agent just like AEPD played a quiet but vital role. That reliability doesn’t just save money. Patients depend on consistent results, especially for life-long treatments.
AEPD also finds a place in cutting-edge coatings and resins. Manufacturers count on it to give paints and polymers extra resilience. In my garage, I’ve mixed two-component epoxy coatings for hobbies and home repair projects. Adding a compound like AEPD prevents sagging or film defects, making surfaces tougher and longer-lasting. That tough finish on pre-finished wood flooring or garage paint owes something to this little chemical’s stabilizing hand.
One of the most important things about AEPD is its toxicity profile. Some chemicals that do similar work come with harsh warnings or major environmental baggage. I always check safety data sheets before starting any project at my bench. Compared to some of its cousins in the buffer family, AEPD sits in a middle ground—manageable if handled responsibly. This makes it a practical option across fields where environmental and worker safety cannot be ignored.
Farmers and hydroponics experts use substances like AEPD to manage acidity in nutrient solutions. Crops respond better when minerals remain available at a reliable pH. Yield gains, reduced waste, and healthier plants result. Small gardens and large greenhouses both benefit from getting chemistry right, even when the weather can’t be controlled.
Plenty of companies are looking for ways to replace old ingredients that pollute or break down too fast. AEPD brings predictability to production lines without adding unnecessary headaches for regulators and workers. Engineers love tools that free them to tweak formulas or run tests with minimal downtime or risk. In my own tinkering, a little flexibility goes a long way. Swapping out AEPD would mean more uncertainty and, likely, more downtime troubleshooting new mixtures.
We talk a lot about finding greener alternatives. AEPD is not perfect. Down the line, better disposal practices, tighter manufacturing controls, and continued transparency about risks will be important as demand rises. Luckily, attentive regulatory oversight and consumer scrutiny keep the industry on track. Looking ahead, I expect the conversation around chemical safety and efficiency to keep evolving, with AEPD playing a steady—if unsung—role in the background.
2-Amino-2-ethyl-1,3-propanediol rarely comes up in daily conversation, but its chemical backbone has roots in both science and industry. This compound carries a strong reputation in buffer solutions, pharmaceutical research, and resin manufacturing. The real value lies in understanding its chemistry, especially for anyone who has ever worked in a lab or tinkered with organic molecules.
The molecular formula of 2-Amino-2-ethyl-1,3-propanediol is C5H13NO2. The backbone consists of five carbon atoms, thirteen hydrogens, one nitrogen, and two oxygen atoms. Structurally, this molecule features a central carbon bonded to an amino group (NH2), an ethyl group (C2H5), and two hydroxymethyl groups (CH2OH) at the terminals. Taking pen to paper, the structure forms as:
CH2OH–C(NH2)(C2H5)–CH2OH
So, the molecule comes with two alcohol groups flanking a central carbon, which also holds an amino and an ethyl group. This layout lets it act as a base, a nucleophile, and a ligand, meaning it can adapt to several chemistry tasks. Anyone who has spent hours balancing reactions or modifying buffer conditions will find 2-AEPD refreshingly versatile.
Organic structure is the difference between a healthy buffer and a ruined experiment. Two hydroxyl groups and that central amino nitrogen hand 2-Amino-2-ethyl-1,3-propanediol a broad chemical toolkit. In my research days, stability in solutions meant less time troubleshooting. The alcohol groups grant water solubility, while the amino group offers basicity. I found this blend invaluable when prepping biological buffers, especially when pH drift could mean the difference between dead cells and a thriving line. Chemical structure directly affected performance — in the lab, that often determined whether data made sense or not.
Safety always comes first. Handling 2-AEPD, lab coats and proper eye protection became routine since the compound can irritate the skin or eyes if accidents happen. I’d check the safety data sheet before opening a new container. As far as environmental effects go, C5H13NO2 is not regarded as acutely toxic or persistent, which scores a point for greener chemistry practices. Modern labs, aiming for sustainable protocols, value compounds that combine effectiveness with a reasonable safety profile.
Even practical reagents face hurdles. Consistent purity tops the list—impurities in a biochemical buffer could lead to unreliable cell responses. Investing in higher grade batches lowers the risk. Waste disposal also raises questions, especially for high-throughput labs. Support for safe chemical recycling programs serves as one approach. Scientists keen on sustainability continue to track the environmental profile of compounds like 2-AEPD, while also exploring alternatives when scale-up threatens green goals.
Chemistry keeps evolving, driven by both classic molecules and new green mandates. For many scientists and manufacturers, success often depends on a detailed grasp of molecular structure. Anyone who’s ever hit a wall in the lab knows the best reagents work because of the small details—one extra carbon or functional group can unlock new applications and foster safer, cleaner results for all involved.
2-Amino-2-ethyl-1,3-propanediol, often used in labs and some industrial settings, looks like a stable white powder. You’ll find it in buffer solutions, in chemistry classrooms, and sometimes in cosmetics or pharmaceuticals. This chemical helps control pH or acts as a building block for more complex compounds.
Most folks working around chemicals want straight facts. According to safety data sheets, this chemical won’t explode or catch fire but brings health risks all the same. Breathing in its dust, getting it on your skin, or accidentally swallowing some—none of these routes are harmless. Animal testing backs this up, showing that swallowing large amounts or breathing high concentrations can irritate the nose, lungs, and stomach.
I’ve spent hours in labs and the truth always hits after handling any chemical for long enough: long-term skin and eye exposure causes big problems, especially if you get complacent. Eyes get red and watery. Skin dries out and may blister. The label usually says “irritant”—that may sound mild, but for anyone with allergies or sensitive skin, trouble arrives fast. Even if your work involves gloves and goggles, a careless moment is all it takes.
You won’t find news stories about mass poisonings or dramatic accidents linked to 2-Amino-2-ethyl-1,3-propanediol. But absence of disasters doesn’t mean zero risk. I’ve seen formulas carelessly mixed by students who forget a mask or don’t respect the warning symbols. Shortness of breath, headaches, and sore throats follow. This feels especially relevant today, since more people experiment with homemade cosmetics or chemistry kits, often without a solid grasp of toxicology.
Data from manufacturer safety sheets warns of “moderate toxicity” if enough enters the body, plus strong reminders to avoid contact with eyes. The EPA lists this substance as neither carcinogenic nor acutely toxic in small doses, but it encourages limited exposure and careful disposal. Every credible guideline emphasizes proper ventilation, gloves, and protective eyewear.
Chemicals once considered mild or useful sometimes triggered problems years after regular use began. See lead in gasoline, or asbestos in insulation. Trusting only the lack of panic around a substance means missing the point. Responsible chemical handling means sticking to time-tested habits. Always check the label. Read the most up-to-date safety sheets. Clean up spills fast. Dispose of the remains following local rules—no shortcuts.
Schools and hobby stores have a duty to teach respect for all chemicals, including those viewed as “safe.” Young scientists and workers should treat even minor irritants with caution, because long-term exposure stacks up. Goggles aren’t just for show. Gloves are cheap insurance.
No matter the chemical, good habits protect health in the long run. Ventilate the workspace well, especially with powders prone to float or scatter. Wash exposed skin quickly and thoroughly. Store powders in sealed containers, away from food or drink. Label everything. Encourage a culture where even experienced workers double-check processes. If something burns, itches, or smells odd, don’t tough it out—clean up, ventilate, and report the problem.
At the end of the day, 2-Amino-2-ethyl-1,3-propanediol demands clear respect, not casual handling. With smart habits and honest awareness, risky situations rarely develop. That’s the real lesson from a career spent around chemicals: never gamble with health, no matter how ordinary a substance seems.
Ask anyone who’s worked in a busy lab or warehouse: chemicals pick no favorites when it comes to safety. 2-Amino-2-ethyl-1,3-propanediol, sometimes called AEPD, has a technical reputation, but its hazards and quirks aren’t unique. Years of chemistry work have made one thing clear to me—overconfidence leads to accidents. Follow evidence, not just office habits, to keep both people and materials protected.
This compound comes with a high enough melting point, so room temperature storage usually works fine. Yet moisture poses a nagging problem. If the container sweats or takes on water, the quality of AEPD drops, and, in many cases, clumped or degraded product could cause problems downstream. The fix sounds almost too simple: pick a dry spot, away from any direct sunlight or heat source. Typical lab shelves or chemical cabinets do the job well, but store it under lock and key, far from food or daily-use supplies. Just because the bottle still looks clean doesn’t mean the contents are okay for careless handling.
Personal experience tells me chemical storage charts matter. AEPD belongs with organic amines, far away from acids or oxidizers. Storing contrary chemicals side-by-side invites spills and not everyone at work checks every label every time. I’ve seen costly cleanups from “harmless” neighbor mistakes, not to mention the unpleasant experience of breathing in unexpected vapors. So, follow the guidelines: separate storage prevents big messes, by design rather than luck.
Handling AEPD isn’t about full hazmat suits, but proper protection pays off. Gloves (nitrile or neoprene), sturdy goggles, and a clean lab coat act as simple barriers. Even the most familiar chemicals can splatter. A 2018 study from the Journal of Occupational Health shows splash protection prevents over 60% of minor workplace exposures. In my own career, a single pair of gloves once saved me a week of irritation from a careless splash. Wear them, even if you’re just wiping syrupy residue or measuring a scoop.
Though AEPD doesn’t throw off strong fumes under normal conditions, keeping it under a fume hood or in a ventilated room makes sense. Poor airflow lets invisible vapors build up, and anyone who’s spent hours in a tight prep space knows how headaches set in without warning. Testing air quality costs little compared to dealing with chronic exposure complaints.
Labels fade, bottles travel, memories fade even faster. Make labeling loud and clear, not just for you but for that new intern who thought everything in Building B was sugar. Include product name, hazards, and a date. Add emergency contacts to storage areas—a step recommended by industrial safety agencies—since nobody likes scrolling for phone numbers after something goes wrong. Safety showers and eyewash stations should always sit nearby, checked monthly, not just after an incident.
Rules only work if people remember and use them. Share best practices, review incident reports openly, and give everyone time to ask questions. During routine drills, walk through what happens if a bottle drops or a cap cracks. Close calls turn into learning opportunities, and those stories stick better than signs on a door. When everyone respects the risks of 2-Amino-2-ethyl-1,3-propanediol, the whole team works safer, and nobody finishes the day wishing they’d paid more attention.
I spent time in a research lab, and buffer solutions shape the backbone of nearly every experiment. If you look at commonly used buffers, you’ll spot 2-Amino-2-ethyl-1,3-propanediol as an ingredient. It keeps pH stable, especially in sensitive biological and biochemical processes. Without proper buffering, proteins break down, reactions drift off-course, and research fails. Laboratories depend on consistency, and this compound offers stable pH control without strong odor or toxicity.
Drug manufacturing walks a tightrope with its formulation work. Many tablets, creams, and injectables rely on certain chemicals to keep drugs active and stable. 2-Amino-2-ethyl-1,3-propanediol often works as a buffering agent in pain relievers or antibiotics, ensuring each dose delivers the same effect. The U.S. FDA lists it as a safe ingredient in several approved medications. Problems in drug stability can cost both lives and money, so this isn’t just background detail—it’s a matter of public health.
Electronics manufacturing looks easy from the outside, but inside those devices sits a web of tiny problems waiting to happen. Printed circuit boards pick up static charges or develop corrosion over time. Manufacturers use specialized cleaning agents, and 2-Amino-2-ethyl-1,3-propanediol acts as a corrosion inhibitor or a pH stabilizer in those cleaning fluids. If you open up a device several years old and find its circuits still clean, this chemical deserves some of the credit for that longevity.
It’s strange how often personal care products owe their success to quiet chemistry. Shampoos, creams, and lotions often contain pH stabilizers and emulsifiers. When formulating these, I’ve seen 2-Amino-2-ethyl-1,3-propanediol recommended for pH adjustment. Skin reacts badly to products that swing far from neutral pH. Skin care manufacturers rely on this ingredient to make sure formulas don’t cause irritation or go rancid on store shelves. Regulatory approval doesn’t come easy, so its consistent use reflects years of safety data.
Walk through a factory or print shop and you’ll notice that stable chemicals keep businesses running. Paints, inks, and coatings need the right texture and drying characteristics to work on many surfaces. Certain companies use 2-Amino-2-ethyl-1,3-propanediol as a neutralizer to avoid using harsher alkalis like ammonia. It helps deliver a smoother finish, fewer odors, and less skin sensitivity in end products. Down the line, it supports both worker safety and customer satisfaction.
Risks exist. Improper handling can lead to health impacts, especially for workers in industrial settings. Solutions start with proper handling instructions, tight regulation, and smarter formulation. The chemical industry has shifted toward environmental responsibility. Waste disposal requires strict standards to avoid pollution, so manufacturers invest in closed systems and robust training.
Looking ahead, folks keep searching for greener alternatives, but today, 2-Amino-2-ethyl-1,3-propanediol solves real, concrete problems across industries. Its reliability shows up quietly in everything from prescription bottles to smartphones—a testament to years of trust built on science and regulation.
