Used as a key building block in the synthesis of high-performance polymers and metal-organic frameworks (MOFs), particularly those designed for gas storage, separation, and catalysis. Its rigid aromatic structure and dual amine groups enable strong coordination with metal ions, enhancing framework stability. Also employed in the development of fluorescent materials and sensors due to its intrinsic photoluminescent properties. In polymer chemistry, it acts as a diamine monomer for producing aromatic polyamides and polyimides with improved thermal and mechanical properties. Additionally, explored in dye and pigment synthesis for specialty applications requiring thermal stability and color fastness.
