Product Code：SP8004
Product Name：TRIMETHYLCHLOROSILANE
Product Introduction：
Trimethylchlorosilane is a monofunctional chlorosilane used as an end-blocker and silylating agent. It caps reactive silanol ends in silicone polymer production, controlling molecular weight. It introduces trimethylsilyl (TMS) protecting groups for alcohols, amines, and thiols in organic synthesis. This moisture-sensitive liquid also hydrophobically modifies fillers and surfaces.
