Used as a key intermediate in the synthesis of high-performance polymers, particularly in the production of polyimides and polyamides. Its structure contributes to thermal stability and mechanical strength in the resulting materials, making it valuable in aerospace, electronics, and insulation applications. Also employed in the development of photoresists and other photo-sensitive materials for semiconductor manufacturing due to its electron-donating properties and ability to form stable radical cations. Additionally, it finds use in organic light-emitting diodes (OLEDs) as a hole-transport material because of its favorable energy levels and film-forming characteristics.
