Used as a high-performance diamine monomer in the synthesis of advanced polyimides and polyamides, offering excellent thermal stability and mechanical strength. Commonly applied in aerospace, microelectronics, and optoelectronic materials due to its rigid aromatic structure and good solubility. Also serves as a building block in conjugated polymers for organic semiconductors and sensors, enhancing electron transport and luminescent properties. Its strong electron-withdrawing oxadiazole core improves oxidative stability in demanding environments.
