Tert-Butylaminoethyl Methacrylate, often abbreviated as TBAEMA, brings a distinct combination of chemical features that calls for close attention in both research and manufacturing settings. At its core, TBAEMA is a methacrylate monomer with an amino-functional tert-butyl group attached, giving it a molecular formula of C10H21NO2 and a molecular weight of about 187.28 g/mol. This unique structure shapes its role in polymer science, cosmetics, coatings, adhesives, and specialty materials. The CAS Number for TBAEMA helps with precise identification: 55719-45-8. The product often shows up as a clear to slightly yellowish liquid at room temperature, offering good handling flexibility, though it is also available in forms such as crystalline solid or flakes, depending on processing conditions and supplier. It sits under the HS Code 2916140000, which groups it among other acyclic and cyclic carboxylic acids and their derivatives, an important code for customs and import-export classification.
The molecule carries both hydrophobic and hydrophilic qualities. Its backbone features a methacrylate group, which brings the potential for radical polymerization—a key feature for forming durable polymers—while the tert-butylaminoethyl group introduces basicity and bulkiness that impact both reactivity and compatibility with other materials. TBAEMA’s density usually hovers around 0.97–1.01 g/cm³, aligning with many other methacrylate derivatives. Practically, this means storage and mixing steps rarely need extraordinary precautions for weight or volume calculations. This liquid often produces a mild, slightly amine-like smell, a minor but useful sensory marker in quality control. TBAEMA has a boiling point well above 200°C, which discourages rapid evaporation and allows for controlled processing. The melting point sits far below room temperature—solid flakes or pearls only become practical if chilled or specially manufactured. In solution, the monomer combines with solvents such as water, acetone, or other alcohols, which helps with cleaning, blending, or dilution for research and manufacturing.
Researchers and manufacturers recognize TBAEMA in various shapes. Most find the liquid form the easiest to transfer or dose, particularly in precision polymer synthesis. Occasionally, solid states such as flakes or crystalline powder appear, especially under cool storage or specialized drying; these forms resist spontaneous clumping, but need airtight containers to avoid absorption of water from the air. Powder and pearl forms emerge after additional processing—these sometimes suit specialty uses, like custom compounding or direct blending with plastic or rubber granulates. Crystals, when grown slowly under controlled temperatures, help in X-ray analysis or chemical purity testing, since their sharp melting points reveal whether impurities are present. The broad range of possible forms reflects the versatility of the material and its compatibility with many chemical processes.
In real-world laboratories and production lines, the material displays a rare combination of reactivity, stability, and adaptability. The methacrylate group delivers a fast, reliable pathway to bigger polymer chains, which see use in paints, adhesives, medical devices, and hydrogels. The tert-butylaminoethyl segment doesn’t just bring shape or basicity—engineers appreciate its potential to change the permeability, softness, or chemical binding of copolymers. TBAEMA’s ability to participate in free radical polymerization expands its appeal, since this kind of chemistry underpins many modern plastics and coatings. In practice, these polymers help control how drugs get delivered through membranes, how surfaces resist fouling, how medical adhesives stick (and later release), and how specialty filters separate chemicals. Its density and easy solubility support safe transfer and flexible process engineering. Working with TBAEMA does not often introduce excessive complexity, but those familiar with high-precision chemistry find its stability under moderate heat and humidity gives a reliable baseline for repeatable reaction control. Raw material costs and supply consistency play a big role here; TBAEMA’s established placement in global trade, with a clear HS Code, supports smoother logistics and price tracking across borders.
TBAEMA sits in a class of chemicals that deserve respect in storage and use. Direct skin contact can cause mild irritation. Its vapors, if concentrated, lead to discomfort in the eyes or lungs, though the risk stays low under normal ventilation. Users need gloves and goggles, plus proper fume extraction in tight or poorly ventilated spaces. The material earns hazard statements for eye and skin sensitization, but does not normally carry acute toxicity at small-scale laboratory doses. TBAEMA must stay away from oxidizers, strong acids, and active catalysts unless part of a planned reaction. In most countries, the chemical falls under slightly restrictive rules, with designated storage cabinets, spill kits, and waste disposal procedures laid out in company safety manuals. Its raw form poses little risk of explosion or dangerous reactivity on its own, but improper mixing with incompatible chemicals gets flagged in quality audits. It does not break down easily, so waste must be collected for approved chemical treatment—a standard practice for synthetic monomers worldwide. Fact sheets and supplier documentation back up all claims about hazards, with safety measures often echoing those set for similar methacrylate monomers. As a practical matter, regular users build a routine around sealed containers, clear labeling, and planned waste pickup, which keeps incident rates low even in busy industrial or academic labs.
Manufacturing TBAEMA draws on a well-established set of raw chemicals: tertiary butylamine, ethylene oxide (or similar ethylene sources), and methacryloyl chloride. Industry uses established batch processes for synthesis. Multi-step purification ensures the product meets specifications for purity, molecular weight, and low levels of volatile organics. Specification sheets typically call for purity above 98%, with tightly controlled acid value, minimal water content (often less than 0.1%), and color index measured to avoid off-colors in finished polymers. TBAEMA’s raw material chain leans on steady supplies of petrochemicals, but ongoing supply chain audits in Europe, Asia, and North America watch for price fluctuation and import-export challenges. Its global market presence means price charts and availability quickly reflect swings in feedstock prices or logistics hiccups. Large buyers work with trusted suppliers who offer paperwork on the full chain of production—from raw inputs to quality tests on the finished monomer, including batch-to-batch traceability.
Safety oversight, supply risk, and cost management remain important areas for improvement. Accidental spills, though rare, call for immediate neutralization—standard practice recommends a commercial absorbent, sealed bags, and prompt transport to disposal. Labs and factories upgrade fume hoods and sensor systems to monitor air quality, since methacrylates in vapor form can sensitize sensitive personnel. To address unpredictable supply, users keep backup stock and diversify sources, partnering with both domestic and international chemical suppliers. Environmental solutions include recycling or controlled incineration of waste, backed by regulatory documentation. Researchers searching for greener options turn to bio-based acrylates, but at the moment, TBAEMA’s role as a niche monomer in tough, medical-grade, or specialty polymers remains strong. Continuing education—safety training, regular chemical audits, and transparent incident reporting—builds a culture where accidents and supply interruptions get caught and fixed fast.
Experience working with TBAEMA reveals a material that delivers versatility where it counts. From a research bench to an industrial reactor, its blend of manageable physical properties, clear HS Code, well-characterized hazards, and strong market presence supports both routine manufacturing and advanced innovation. As long as attention stays on safe handling, reliable sourcing, and modern waste controls, Tert-Butylaminoethyl Methacrylate stands as one of the better options for those seeking high-performance methacrylate-based materials.
