Chlorotrimethylsilane, 98%

Description

CAS: 75-77-4 | C3H9ClSi | 108.64 g/mol

Chlorotrimethylsilane is used to silanize laboratory glassware, which makes the surfaces more lipophilic. It is used in the production of trimethylsilyl halides, pseudohalides and various organic silicon compounds. It is also used to produce hexamethyldisilane by reduction.

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.
