Used as a specialty reagent in organic synthesis, particularly in the formation of silicon-nitrogen bonds for advanced materials. It serves as a silylating agent in the development of pharmaceuticals and agrochemicals, where its chloro and diethylamino groups allow for selective functionalization. Its diphenylsilane core contributes to thermal stability, making it suitable for high-temperature reactions. Also employed in the preparation of silane-based coupling agents for surface modification of inorganic materials, enhancing compatibility in composite systems. Limited solubility in water restricts use to anhydrous organic solvents.
