Used primarily as a coupling agent in the synthesis of organosilicon compounds. It is applied in surface modification to enhance adhesion between organic and inorganic materials, particularly in coatings and adhesives. In the production of silica-based materials, it serves as a functionalizing agent to introduce cyanopropyl groups, improving material properties for chromatography applications. It is also employed in the manufacturing of specialty polymers and resins, where it aids in creating tailored surface characteristics. Additionally, it finds use in the preparation of stationary phases for gas chromatography, optimizing separation efficiency.
