Used as a key intermediate in the synthesis of high-performance polymers, particularly in the production of polybenzoxazoles (PBO) and related aromatic heterocyclic polymers. These polymers exhibit exceptional thermal stability, mechanical strength, and flame resistance, making them suitable for advanced composite materials in aerospace, military armor, and high-temperature filtration. Also employed in the development of electroactive materials and conductive polymers due to its electron-rich structure. Shows potential in dye and pigment manufacturing, especially for textiles requiring UV and chemical resistance. Investigated for use in sensors and optoelectronic devices owing to its luminescent properties when incorporated into metal-organic frameworks.
