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.

Tetramethylsilane

CAS: 75-76-3

Tetramethylsilane is a chemical compound that consists of four methyl groups bound to a central silicon atom. Tetramethylsilane has been used in the study of mammalian tissue and in the production of hydrogen gas. It is also used in the analysis of proteins by mass spectrometry. The hydroxyl group on tetramethylsilane reacts with other compounds (e.g., sulfur dioxide) to form an addition compound. Photomultiplier tubes use tetramethylsilane as a reactant, which can be used as a reference gas for flow systems. Tetramethylsilane has high values that are typically found in argon, which can be used to determine whether or not it is present as an impurity.
