Sodium trimethylsiloxide is an organosilicon compound with the formula NaOSi(CH₃)₃. It is the sodium salt of the conjugate base derived from trimethylsilanol.^[1] A white solid, its molecular structure consists of a cluster with Na-O-Na linkages on the basis of closely related compounds.^[2]

The salt is used to prepare trimethylsiloxide complexes by salt metathesis. Trimethylsiloxide is a lipophilic pseudohalide.^[3]^[4]

It is a source of oxide dianion.^[5]^[6]
