Used primarily in the synthesis of high-performance polyimides, this compound contributes to the formation of polymers with exceptional thermal stability and mechanical strength. It is especially valuable in aerospace, microelectronics, and advanced composite materials where resistance to extreme temperatures and harsh environments is critical. The rigid aromatic structure enhances the glass transition temperature and dimensional stability of the resulting polymers. It also finds use in gas separation membranes due to its ability to promote selective permeability and in the development of specialty coatings that require chemical resistance and durability.
