Used as a key intermediate in the synthesis of specialty polymers and resins, particularly in the production of high-performance epoxy curing agents. Its rigid norbornene structure contributes to enhanced thermal stability and mechanical strength in cured epoxy systems, making it suitable for aerospace, electronics, and advanced composite applications. Also employed in the development of functional monomers for ring-opening metathesis polymerization (ROMP), yielding polymers with tailored properties for coatings and engineering plastics. Additionally, it serves as a building block in organic synthesis for pharmaceuticals and fine chemicals due to its reactive anhydride group and well-defined stereochemistry.
