Used as a coupling agent in surface modification of silica, glass, and other inorganic materials to introduce organic functional groups. Enhances adhesion between organic polymers and inorganic substrates in composite materials. Commonly applied in the synthesis of silane-based primers and adhesives for coatings, sealants, and electronic encapsulation. Also serves as an intermediate in the preparation of functionalized silicones and organosilicon compounds used in specialty chemicals and pharmaceuticals. Its reactivity allows for further derivatization in multi-step organic synthesis.
