Used primarily as a coupling agent in the surface modification of materials, particularly in the preparation of silica-based stationary phases for chromatography. It enhances the bonding of organic molecules to inorganic surfaces, improving the performance and stability of chromatographic columns. Additionally, it is employed in the synthesis of organosilicon compounds, where it serves as an intermediate to introduce functional groups onto silicon atoms. This chemical is also utilized in the production of adhesives and sealants, where it improves adhesion properties and durability. Its ability to modify surfaces makes it valuable in coatings and composites, enhancing their mechanical and chemical resistance. In nanotechnology, it is used to functionalize nanoparticles, enabling their integration into various advanced materials and devices.
