Commonly abbreviated TMS, it's the simplest tetraorganosilane. Like all silanes, the SiC4 framework is tetrahedral. TMS is a building block in organometallic chemistry but also finds use in diverse niche applications. Synthesis and reactions TMS is a by-product of the production of methyl chlorosilanes, SiClx(CH3)4−x, via… (More on Tetramethylsilane)
