This compound, tert-Butyl(3-chloropropoxy)dimethylsilane, is a silyl-protected derivative of 3-chloropropan-1-ol, featuring a tert-butyldimethylsilyl (TBDMS) group. It functions as a key intermediate in organic synthesis, where the silyl ether protects the hydroxyl group, enabling selective functionalization of the terminal chloride. This is valuable in multi-step reactions for producing pharmaceuticals, agrochemicals, and fine chemicals. Furthermore, it serves as a building block in silane chemistry for creating coupling agents, siloxanes, and modified polymers. Applications include surface modification to improve hydrophobicity, adhesion, and chemical/thermal resistance in coatings, adhesives, composites, and advanced materials.
