Used as a key intermediate in the synthesis of liquid crystal materials for display technologies. Its rigid biphenyl structure and electron-withdrawing trifluoromethyl group enhance thermal stability and mesomorphic properties. Also employed in pharmaceutical research as a building block for bioactive molecules, particularly in development of anti-inflammatory and antiviral agents. The carboxylic acid functionality allows for easy derivatization, making it valuable in combinatorial chemistry and structure-activity relationship studies.
