Used primarily as a crosslinking agent in the production of polymers, enhancing their thermal stability and mechanical properties. It is also employed in the synthesis of specialty chemicals, where it acts as a key intermediate for creating compounds with specific functionalities. In the pharmaceutical industry, it serves as a reagent for developing drug molecules, particularly in the formation of complex organic structures. Additionally, it finds application in the preparation of high-performance materials, such as resins and adhesives, due to its ability to form strong covalent bonds. It is further utilized in photosensitive materials as a photosensitizer for applications in printing, photography, and lithography.
