Used as a key building block in the synthesis of high-performance polymers, particularly in the production of polyimides and polyamides. Its rigid aromatic structure and amine functional groups enable the formation of thermally stable and mechanically strong materials suitable for aerospace, electronics, and advanced composite applications. Also employed in the development of specialty resins and coatings requiring resistance to heat and chemicals. Additionally, it serves as a precursor in the fabrication of organic semiconductors and optoelectronic materials due to its conjugated framework and electron-transport properties.
