Used as a silylating agent in organic synthesis, particularly for the protection of hydroxyl and carboxyl groups during multi-step reactions. Its steric bulk and electron-rich structure make it effective in selective functional group transformations, especially in pharmaceutical and fine chemical manufacturing. Also employed as an intermediate in the preparation of more complex organosilicon compounds used in materials science, including silicon-based polymers and hybrid organic-inorganic materials. Shows utility in surface modification of silica and other oxide materials, enhancing hydrophobicity and compatibility with organic matrices in composite formulations.
