Used as a silylating agent in organic synthesis, particularly for introducing silyl groups to protect hydroxyl or other functional groups during multi-step reactions. Its reactivity makes it valuable in the preparation of intermediates for pharmaceuticals, agrochemicals, and specialty silicones. Commonly employed in the manufacture of silane coupling agents that enhance adhesion between organic and inorganic materials in composites, coatings, and sealants. Also utilized in the surface modification of silica and glass to alter hydrophobicity or improve compatibility with polymer matrices.
