Tetramethylsilane | C4H12Si - PubChem
Tetramethylsilane, also known as TMS or Si(CH3)4, is classified as a hydrocarbon derivative or a hydrocarbon derivative. Hydrocarbon derivatives are derivatives of hydrocarbons obtained by substituting one or more carbon atoms by an heteroatom. They contain at least one carbon atom and heteroatom. TMS can be found in humans.
