Used primarily as a monomer in the production of high-performance polymers, particularly polyimides. These polymers are essential in the electronics industry for manufacturing flexible printed circuits, insulating films, and coatings due to their thermal stability and mechanical strength. It also serves as a precursor in the synthesis of epoxy resins, which are widely used in adhesives, coatings, and composite materials for aerospace and automotive applications. Additionally, it finds use in the development of specialty fibers and films that require high durability and resistance to extreme conditions.
