Used as an intermediate in the synthesis of high-performance polymers and specialty resins due to its rigid aromatic structure and functional acetyl groups. The compound enables the development of thermally stable and mechanically strong materials, making it suitable for aerospace, electronics, and composite applications. Its reactivity allows for derivatization into bisimides or diamines, which are key building blocks in polyimides and polyamides. Also explored in liquid crystal chemistry and as a precursor in pharmaceutical research where biphenyl ethane frameworks are relevant.
