Used primarily in the production of high-performance polymers, particularly polyimides, which are essential in the electronics industry for manufacturing flexible printed circuits and insulating films. It serves as a key monomer in the synthesis of these polymers, contributing to their thermal stability and mechanical strength. Additionally, it is employed in the development of advanced composite materials for aerospace applications, where durability and resistance to extreme conditions are critical. Its role in creating adhesives and coatings that withstand high temperatures also makes it valuable in industrial settings.
