Used primarily as a crosslinking agent in polymer chemistry, this compound enhances the thermal and mechanical stability of resins and coatings. Its multiple isonicotinate groups readily participate in curing processes, making it valuable in the formulation of high-performance adhesives and composite materials. It is also employed in the synthesis of functional polymers for biomedical applications, such as drug delivery systems, due to its ability to form degradable networks under controlled conditions. Additionally, it finds use in photo-curable systems where UV-induced polymerization is required, offering rapid curing with improved material toughness.
