CAS 75-76-3 — Tetrametilsilano

Tetramethylsilane (TMS) is a clear, volatile liquid organosilicon compound widely used as an internal reference standard in nuclear magnetic resonance (NMR) spectroscopy due to its single, sharp signal. It also serves as a calibration marker in gas chromatography and a precursor in chemical synthesis. CAS 75-76-3, molecular formula Si(CH3)4, molecular weight 88.22 g/mol. Store between 2–8 °C. Hazard classification includes a signal word of *Danger* (corrosive, flammable). Molekula supplies Tetramethylsilane from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
