This chemical is primarily used as a silane coupling agent in the surface treatment of materials. It is applied to modify surfaces, particularly glass or silica, to enhance adhesion properties for coatings, adhesives, or composites. It is also utilized in the preparation of stationary phases for gas chromatography, where it helps improve the separation of complex mixtures. Additionally, it serves as an intermediate in the synthesis of other organosilicon compounds, which are essential in various industrial and research applications. Its ability to introduce cyanopropyl groups makes it valuable in creating specialized materials with tailored properties.
