Used as a silylating agent in organic synthesis, particularly in the protection of hydroxyl and amino groups during multi-step reactions. Its chloromethyl functionality allows for further crosslinking or anchoring to solid supports, making it valuable in the preparation of functionalized silica gels or polymer resins for catalysis and chromatography. Commonly employed in the manufacturing of specialty silanes for adhesives, coatings, and sealants where moisture resistance and adhesion promotion are critical. Also finds use in the synthesis of intermediates for pharmaceuticals and agrochemicals due to its selective reactivity and stability under controlled conditions.
