Grade: CG-3101
Methoxytrimethylsilane
CG-3101 (Methoxytrimethylsilane) is used as a terminating agent for polysiloxanes. It can serve as a precursor to modify the crosslinking density inside aerogels, thereby imparting flexibility to the aerogel. It can also be used as a silylating agent.

Application
CG-3101 is used as a blocking agent / end-capping agent for polysiloxanes.
CG-3101 can serve as a precursor to modify the crosslinking density inside aerogels, thereby imparting flexibility. Flexible SiO2 aerogels are prepared by adjusting the ratio of trimethoxymethylsilane to solvent, followed by selection of appropriate phase
CG-3101 can also be used as a silylating agent for protecting hydroxyl, amino, and carboxyl groups without releasing ammonia or hydrogen chloride, making it highly valuable in the synthesis of pharmaceutical intermediates.
