3-(Triethoxysilyl)propyl methacrylate(CAS: 21142-29-0)

3-(Triethoxysilyl)propyl methacrylate (CAS: 21142-29-0) is a colorless to light yellow viscous liquid. It has a molecular weight of approximately 314.4 g/mol and is poorly soluble in water but miscible with organic solvents. It exhibits good reactivity, particularly towards silanes, making it useful in coupling applications.

3-(Triethoxysilyl)propyl methacrylate (CAS: 21142-29-0) is typically synthesized by the reaction of 3-aminopropyl methacrylate with triethoxy silane. The process involves the displacement of the amine group with a silyl group, using a catalyst such as triethylamine to facilitate the reaction. The yield is generally high, and the product is isolated by distillation.

3-(Triethoxysilyl)propyl methacrylate (CAS: 21142-29-0) is widely used in the pharmaceutical industry for drug delivery systems, in polymer science for the modification of polymer surfaces, in sensor technology for functional coatings, and in semiconductor manufacturing for surface treatments.

When handling 3-(Triethoxysilyl)propyl methacrylate (CAS: 21142-29-0), proper personal protective equipment (PPE) should be worn, including gloves and eye protection. Work should be conducted in a well-ventilated area or a fume hood. Spills should be cleaned up using appropriate absorbents, and the area should be thoroughly washed. Always consult the Safety Data Sheet (SDS) for detailed information and emergency procedures.
