Description

CAS: 10025-78-2 | Cl3Si | 134.435 g/mol

Trichlorosilane is used to prepare silicon for semiconductors. It is an active ingredient used in the preparation of polysilicons and silicone resins. It acts as coupling agents and silane adhesion promoter. It is a precursor to prepare organosilicon compounds through hydrosilylation reactions. Further, it is involved in the preparation of octadecyltrichlorosilane, perfluoroctyltrichlorosilane, and perfluordecyltrichlorosilane.

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.
