Used as a key intermediate in the synthesis of liquid crystal materials, particularly in the production of advanced display technologies. Its rigid biphenyl core and ester functional groups contribute to thermal stability and mesomorphic properties when incorporated into liquid crystal formulations. Also employed in organic synthesis for developing specialty polymers and photoresponsive materials due to its conjugated structure and ability to undergo derivatization. Its solubility in common organic solvents makes it suitable for solution-based processing in electronic and optoelectronic applications.
