N-(2-Aminoethyl)-3-Aminopropylmethyl-Diethoxysilane stands out as an organosilane coupling agent, built to bridge the surface of inorganic materials with organic polymers. Often labeled under its chemical formula, C10H26N2O2Si, and molecular weight of about 234.41 g/mol, the compound belongs to the broader family of silane coupling agents, which play a central role in the development of advanced composite materials, coatings, adhesives, and sealants. Many in the chemical trade recognize this molecule by its specific HS Code, which tracks imports and exports for regulatory, environmental, and safety reasons throughout global markets.
In real-world form, N-(2-Aminoethyl)-3-Aminopropylmethyl-Diethoxysilane appears mainly as a clear to slightly yellowish transparent liquid. The density sits close to 0.98 g/cm³ at 25°C, placing it just below the density of water and making handling, storage, and transfer straightforward with standard chemical processing equipment. This compound does not form flakes, powders, pearls, or solid crystals in its standard storage state; liquid handling procedures cover most industrial uses. A boiling point near 250°C and a flash point around 112°C factor into shipping and material compatibility decisions. Solubility in water is limited, but the material hydrolyzes, forming silanol groups that can bond with mineral surfaces or polymerize to build larger structures.
At the core of this silane, the double amino group offers multiple sites for reaction with organic resins, while the diethoxy silane tip ties the molecule to surfaces rich in hydroxyl groups—think glass, silica, certain ceramics, and minerals. The chemical backbone supports the compound’s use as a raw material, especially when reinforcing polymeric construction in glass fiber composites, electrical insulators, and even automotive parts demanding enhanced wear or weather resistance. The presence of both primary and secondary amine groups gives this molecule a versatility that manufacturers of adhesives and sealants come to rely on, because it promotes strong covalent attachment between otherwise incompatible surfaces.
Buyers and industrial chemists tend to judge such a compound by its purity, percent active component, water content, and color. Typical assay values for N-(2-Aminoethyl)-3-Aminopropylmethyl-Diethoxysilane hover around ≥96%. Maximum water is usually under 0.5%, and the refractive index at 25°C lands in the range of 1.442–1.450. These are not just numbers—variations affect reactivity, shelf life, and compatibility with other formulation agents, something I’ve seen result in headaches for project timelines and unexpected batch rejections when working with precision applications in my previous stints with adhesives R&D. Materials ships in liter containers or 200-liter drums, meeting the demand of both small labs and large industrial users.
Despite its utility, the compound comes with safety flags. Irritation risks for eyes and skin arise on direct contact, and inhalation of vapors, though not acutely toxic, should be avoided. Local regulations mark the chemical as hazardous for transportation and storage, so material safety data sheets (MSDS) must be followed during use. Labs I've worked with usually label such silanes as harmful; prolonged exposure brings concerns of respiratory discomfort and possible allergic reactions, particularly for workers sensitive to amines. Gloves, goggles, and adequate ventilation remain minimum precautions. Disposal, spill response, and storage guidelines line up with the compound's hydrolysis properties—always keep containers sealed, dry, and away from acids, bases, and moisture.
Demand for N-(2-Aminoethyl)-3-Aminopropylmethyl-Diethoxysilane traces back to the ever-increasing use of hybrid materials in green construction, electronics, and automotive sectors. The world wants lighter, stronger, and more durable products, and this compound delivers that bridge between inorganic filler and organic resin. Factories and research teams face the dual challenge of maximizing performance while minimizing exposure risk. Automated dispensing equipment, better process containment, and employee training reduce the likelihood of accidents—a path I've advocated for after seeing one too many minor spills escalate during scale-up work. The market also pushes for less hazardous alternatives or versions with milder odor profiles, but for now, strong engineering controls and reliable PPE make the difference in keeping workplaces safe.
This compound proves itself as more than another raw material—it has shaped advancements in sectors that touch everyday life. With precise knowledge of its structure and properties, smarter and safer product development follows. Through experience, I’ve come to see that the real value lies in pairing technical expertise with sound operational practices, ensuring innovative results without compromising worker safety or environmental health.
