Tetramethylsilane (abbreviated as TMS) is the organosilicon compound with the formula Si(CH3)4. 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. Visa mer TMS is a by-product of the production of methyl chlorosilanes, SiClx(CH3)4−x, via the direct process of reacting methyl chloride with silicon. The more useful products of this reaction are those for x = 1 ( Visa mer Tetramethylsilane is the accepted internal standard for calibrating chemical shift for H, C and Si NMR spectroscopy in organic solvents (where TMS is soluble).
