Used as a coupling agent in hybrid material synthesis, this compound links organic and inorganic phases, particularly in sol-gel processes. It enhances adhesion between polymer matrices and silica-based surfaces, making it valuable in coatings, composites, and sealants. Its carboxylic and amide functional groups allow coordination with metal oxides and participation in hydrogen bonding, improving mechanical stability and dispersion in nanomaterials. Also employed in surface modification of nanoparticles and biosensors, where controlled interfacial interactions are critical.
