Used in the production of high-performance polymers, particularly polyimides, which are essential in the electronics industry for flexible printed circuits and insulating films. It serves as a key monomer in synthesizing heat-resistant materials, making it valuable for aerospace applications where thermal stability is critical. Additionally, it is employed in the manufacture of coatings and adhesives that require durability and resistance to harsh environmental conditions. Its role in creating advanced materials also extends to optical applications, such as light-emitting diodes (LEDs) and liquid crystal displays (LCDs).
