Applications
Dichloromethylphenylsilane is used as a monomer (‘building block’) in the production of silicone polymers or silicone resins. Silicone polymers may be oils, greases and rubbers. It is also used as an intermediate (starting material) in the production of other organosilicon substances. It is a bifunctional reagent for the preparation of methylphenylsilyl derivatives of diols.

Solubility
Reacts with water.
