Trimethylsilyl chloride, also known as chlorotrimethylsilane is a silyl halide, with a variety of different uses in chemistry. It has the formula (CH3)3SiCl, and under standard conditions it is a colourless liquid, which is stable in the absence of water. It can be prepared from silicon tetrachloride by nucleophillic substitution of three of the chloride groups with a nucleophillic methyl source such as methyllithium, however the compound is readily available commercially.
