Used primarily as a key monomer in the synthesis of high-performance polymers, particularly polyimides. These polymers are valued for their exceptional thermal stability, mechanical strength, and chemical resistance, making them ideal for applications in the electronics industry, such as flexible printed circuit boards, insulating films, and semiconductor coatings. Additionally, it is employed in the production of advanced composites used in aerospace and automotive industries, where materials must withstand extreme temperatures and harsh environments. Its role in creating heat-resistant adhesives and coatings further extends its utility in industrial and engineering applications.
