Tetramethylsilane (abbreviated as TMS) is the organosilicon compound with the formula Si(CH3)4. It is a colorless liquid. It is the simplest tetraorganosilane. Like all silanes, the TMS framework is tetrahedral. TMS is a building block in organometallic chemistry but also finds use in diverse niche applications.
