CAS 75-76-3: Tetramethylsilane

Description: Tetramethylsilane (TMS) is a colorless, odorless, and highly volatile organosilicon compound with the chemical formula Si(CH₃)₄. It is characterized by its tetrahedral molecular structure, where a silicon atom is bonded to four methyl groups. TMS is widely used as a reference standard in nuclear magnetic resonance (NMR) spectroscopy due to its ability to provide a consistent chemical shift for protons and carbons, making it invaluable in organic chemistry for determining the structure of compounds. It is also non-toxic and has low reactivity, which makes it suitable for various applications, including as a solvent and in the synthesis of other silicon-containing compounds. TMS has a low boiling point and is highly soluble in organic solvents, but it is insoluble in water. Its chemical stability and inertness under standard conditions contribute to its utility in laboratory settings. However, it should be handled with care due to its flammability and potential health hazards when inhaled or ingested.
