Exo-5-Norbornenecarboxylic acid is widely used in organic synthesis and polymer chemistry. Its norbornene structure makes it a valuable monomer for producing high-performance polymers through ring-opening metathesis polymerization (ROMP). These polymers exhibit excellent thermal stability and mechanical properties, making them suitable for coatings, adhesives, and advanced materials in aerospace and electronics. Additionally, its carboxylic acid group allows for further functionalization, enabling the creation of tailored polymers or small molecules for pharmaceutical and agrochemical applications. It also serves as a building block in the synthesis of complex organic compounds, particularly in the development of catalysts and ligands for asymmetric synthesis.
