Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of central nervous system (CNS) active compounds. Its structure supports the creation of heterocyclic frameworks found in certain anticonvulsant and neuroprotective drugs. The carboxylic acid functionality allows for easy derivatization, enabling the formation of amides, esters, and other functional groups important in drug design. It is also employed in research settings to explore structure-activity relationships in isoxazole-based bioactive molecules.
