Audited Supplier Tetramethylsilane (TMS) is an organosilicon compound with the chemical formula (CH3)4Si. It is a colorless liquid that is primarily used as a reference standard in nuclear magnetic resonance (NMR) spectroscopy.
TMS is commonly employed as an internal standard in NMR analysis because it exhibits a single, well-defined peak in the NMR spectrum. This peak is assigned a chemical shift of 0 ppm and is used as a reference point for determining the chemical shifts of other compounds in the same NMR experiment. The chemical shift values of other signals in the spectrum are measured relative to the TMS peak.
One of the reasons TMS is widely used as an NMR standard is because it is relatively inert and non-toxic. It does not readily react with most chemicals, making it suitable for use as a reference compound in a variety of organic and inorganic solvents.
TMS is also utilized in other areas, such as as a solvent for certain reactions and as a starting material for the synthesis of other organosilicon compounds. Additionally, TMS can function as a protective group in organic synthesis, where it can be attached to reactive functional groups to prevent undesired reactions.
Overall, TMS plays a crucial role in NMR spectroscopy as a reference standard and finds applications in various chemical and scientific research fields.
