This chemical is primarily used in the field of polymer chemistry as a curing agent for epoxy resins. It enhances the thermal stability and mechanical properties of the cured epoxy, making it suitable for high-performance applications such as coatings, adhesives, and composite materials. Additionally, its reactive anhydride group allows it to participate in crosslinking reactions, improving the durability and chemical resistance of the final product. It is also employed in the synthesis of specialty chemicals and intermediates for advanced material development.
