Used as a silylating agent in organic synthesis, particularly for the protection of hydroxyl and carboxyl groups during multi-step reactions. Its bulky structure enhances selectivity in functional group transformations, making it valuable in the synthesis of complex molecules such as pharmaceuticals and natural products. Also employed in surface modification of silica-based materials to increase hydrophobicity, useful in coatings, adhesives, and specialty polymers. The presence of bromophenyl and silyloxy groups allows further functionalization via cross-coupling reactions, expanding its utility in developing advanced organosilicon compounds.
