Used primarily in the synthesis of organosilicon compounds, it serves as a key intermediate in the production of silicone polymers and resins. Its reactive chloromethyl group allows for further functionalization, making it valuable in creating tailored materials for coatings, adhesives, and sealants. Additionally, it is employed in the development of surface-modifying agents, enhancing properties like water repellency and chemical resistance in various industrial applications. Its role in cross-linking reactions also makes it useful in the manufacture of high-performance elastomers and composites.
