Used as a key intermediate in the synthesis of liquid crystal monomers, particularly in the production of reactive mesogens for advanced display technologies. Its allyl group enables efficient radical polymerization, making it valuable in crosslinking systems for optical films and alignment layers. Also employed in pharmaceutical research as a building block for ester and amide derivatives due to its carboxylic acid functionality. Additionally, it serves in polymer modification to enhance thermal and mechanical properties through functional side chains.
