Used primarily as a chemical intermediate in the synthesis of high-performance polymers and resins. It reacts with various alcohols and amines to form esters and amides, which are key building blocks in producing polyimides and polyurethanes. These materials are valued for their thermal stability and mechanical strength, making them suitable for aerospace, electronics, and insulation applications. Also employed in the manufacture of flame-retardant coatings and wire enamels due to its ability to enhance thermal and oxidative resistance. Its reactivity allows for cross-linking in coating formulations, improving durability and chemical resistance.
