Used primarily in the production of high-performance polymers, particularly polyimides, which are known for their thermal stability and mechanical strength. These polymers are applied in the manufacturing of flexible printed circuit boards, insulating films, and coatings for aerospace and electronics industries. Additionally, it serves as a precursor in the synthesis of organic semiconductors, which are essential in the development of electronic devices like OLEDs and solar cells. Its ability to form stable, heat-resistant materials makes it valuable in advanced material science applications.
