Application

Chloropentamethyldisilane may be used as one of the constituents for the sythesis of silyloxyjulolidine (SiN1) as a source of silyl radicals which may be used as photoinitiators for free radical photopolymerization. It may also be used in the preparation of 2-pentamethyldisilanyloxymethyl)phenylpentamethyldisilane.
