Chloromethyltriethoxysilane Description

Chloromethyltriethoxysilane is a chlorine-containing compound widely used as an essential intermediate in the synthesis of functional silanes and silicone compounds. Also known as triethoxychloromethylsilane, it reacts vigorously with compounds containing active hydrogen, releasing hydrogen chloride. This compound serves as a key raw material for the production of Phenylaminomethyltriethoxysilane (CAS No. 3473-76-5) and Diethylaminomethyltriethoxysilane (CAS No. 15180-47-9).
