Innehåll

trimethylchlorosilane (trimethylchlorosilane) is a colorless transparent liquid with irritating odor and exposure in the air, easy and moisture reaction to produce hydrogen chloride, soluble in benzene, ether and perchloroethylene, is an excellent reagent in the introduction of trimethylsilyl in organic molecules. Due to the reaction of linking and removing trimethylsilyl groups, trimethylsilyl groups can be said to be protective groups of functional groups such as hydroxyl groups, carboxyl groups, and amino groups.

chlorotrimethylsilane has the advantages of high yield, mild conditions and wide application range, it is widely used in the synthesis of spices and organic drugs, and its demand is increasing. Trimethylchlorosilane is mainly converted from trimethylsilyl ether.

This product is mainly used as an intermediate for the production of silicone polymers and other products, and also used as a raw material for polymer compound head agent, desiccant, dehydrating agent, high temperature adhesive and resin. In the pharmaceutical production for the synthesis of cephalosporin I, cephalosporin V.

This product can be used to produce a variety of organic silicon compounds, is the main raw material for the production of hexamethyldisilazane and hexamethyldisiloxane. This product can be used to prepare alkylating agent, also can be used as a group protective agent in the production of pharmaceutical and chemical industry.
