Diphenylsilanediol is a very useful intermediate for the synthesis of organic silicon materials. It can be used to synthesize octa-phenylcyclotetrasiloxane. can produce silicone resin or inorganic - organic silicone polymer by condensation reaction,giving these materials good excellent mechanical and thermal properties and a variety of special optical properties. Some studies have shown that the birefringent index of waveguide can be reduced by sol-gel polymer synthesized from diphenylsilanediol. Diphenylsilanediol is an early used surface modifier of white carbon black, which is characterized by high reaction temperature, long reaction time and selectivity of the surface active hydroxyl group.

Diphenylsilanediol can be used as silicone rubber structure control agent to reduce the structuralization phenomenon of silicone rubber and improve the processing performance of silicone rubber; Can be used for synthesis of phenyl silicone oil, phenyl silicone resin, phenyl silicone rubber; It can also be used as modified intermediates of polyurethane resin, epoxy resin, acrylic resin, PP, PET, PE, etc., endossing new products with high and low temperature resistance, radiation resistance, aging resistance and other properties
