Used in the synthesis of functional polymers and resins due to its reactive vinyl and pyridine groups. Commonly employed in producing ion-exchange membranes and adsorbents for metal ion recovery. Serves as a crosslinking agent in specialty coatings and adhesives, enhancing thermal and chemical resistance. Applied in the development of sensors and catalysts where nitrogen coordination is required. Also utilized in surface modification of nanoparticles and in creating antimicrobial coatings. Its ability to coordinate with metals makes it valuable in catalytic systems and in the fabrication of conductive materials. Additionally, incorporated in controlled drug delivery systems as a pH-sensitive carrier for sustained release of active substances.
