Tetramethylsilane, 99.9%, Thermo Scientific Chemicals

Description

Tetramethylsilane is used as a building block in organometallic chemistry. It acts as a by-product in the production of methyl chlorosilanes. Also, it serves as a precursor to silicon dioxide or silicon carbide. It is used as internal reference standard for the calibration of chemical sift for ¹, ¹³ and ²⁹ NMR spectroscopy. In addition, it is used as an aviation fuel.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
