Used primarily as a monomer in the synthesis of specialty polymers and resins, particularly in the production of high-performance polyimides and epoxy resins. Its rigid bicyclic structure enhances thermal stability and mechanical strength of the resulting materials, making them suitable for aerospace, electronics, and advanced composites. Also employed in Diels-Alder reactions as a dienophile in organic synthesis to build complex cyclic structures. Additionally, derivatives serve in developing functional materials such as photoresists and crosslinking agents in coatings.
