Used as an intermediate in the synthesis of organic semiconductors and optoelectronic materials. Its electron-withdrawing trifluoromethyl groups enhance thermal and oxidative stability, making it suitable for applications in OLEDs (organic light-emitting diodes) and perovskite solar cells. Commonly employed in hole-transport materials and as a building block in high-performance polymers for electronic devices. Also finds use in pharmaceutical research due to its unique steric and electronic properties.
