This chemical is primarily used as a coupling agent in the modification of surfaces, particularly in the field of materials science. It is applied to enhance the adhesion between organic and inorganic materials, making it valuable in coatings, adhesives, and composite materials. Additionally, it is utilized in the functionalization of nanoparticles and surfaces to introduce aldehyde groups, which can further react with amines or other functional groups for targeted applications in biosensors, drug delivery systems, and surface engineering. Its silane group allows it to bond effectively with glass, metals, and ceramics, while the aldehyde group provides a reactive site for subsequent chemical modifications.
