Used as a key intermediate in organic synthesis, particularly in the preparation of fluorinated conjugated materials for optoelectronic devices. Its rigid, linear structure and electron-withdrawing trifluoromethyl groups make it valuable in the development of organic semiconductors, liquid crystals, and photovoltaic materials. Commonly employed in Sonogashira coupling reactions to build extended π-systems for use in OLEDs and field-effect transistors. Also explored in pharmaceutical research for modifying molecular stability and lipophilicity in drug candidates.
