Usage

Chlorotrimethylsilane is used as intermediates, hydrophobic agents and reagents for analysis of silicone oil. It is also can used for gas chromatography derivatization reagent for silanization of hydroxyl, amino and carboxyl groups without steric hindrance. It is also used in organic synthesis.

Chlorotrimethylsilane is Silanization reagent for hydroxyl, amino and carbonyl groups. For the preparation of its volatile derivatives for gas chromatography. Ketone alcohol condensation of esters, condensation cyclization of alpha, omega 12 esters, acylation of malonate esters. Iso-like esters are made from carbamic acid vinegar. Enol silane ether is prepared from carbonyl compounds. Enamine from ketone. Reduction silanization of aromatic rings, etc.

Chlorotrimethylsilane is Trimethyl chlorosilane is mainly used to synthesize silane ether compounds and vinyl silane, and can also be used as the protective group of hydroxyl compounds such as alcohols, in addition, it is also used in the de-protective reaction of tertiary butyl oxycarbonyl (BOC).

Chlorotrimethylsilane can be used to produce various organosilicon compounds and is the main raw material for producing hexamethyldisilazane and hexamethyldisiloxane.
