Used primarily as a silylating agent in organic synthesis, enabling the protection of functional groups such as alcohols and amines during multi-step reactions. It is also employed in the production of silicone polymers and resins, where it acts as a cross-linking or chain-extending agent. Its reactivity makes it valuable in surface modification of inorganic materials, improving adhesion and compatibility in composite systems. Additionally, it serves as an intermediate in the manufacture of specialty silanes used in coatings, adhesives, and sealants. Due to its moisture sensitivity, it is effective in generating hydrochloric acid in situ for catalytic or cleavage reactions.
