Used as a silylating agent in organic synthesis, particularly for the protection of alcohols and phenols due to its reactivity with hydroxyl groups. It introduces the benzylsilyl group, which can stabilize reactive intermediates and modify solubility properties of molecules during multi-step syntheses. Commonly applied in pharmaceutical and agrochemical industries where selective functional group protection is required. Also serves as a coupling agent in some polymer systems, enhancing adhesion between organic and inorganic materials. Its byproducts are typically easy to remove, making it favorable in purification processes.
