Used primarily as an intermediate in the synthesis of pharmaceuticals, particularly in the development of antipsychotic and antimicrobial agents. Its structure supports the formation of biologically active compounds that interact with central nervous system receptors. It is also employed in the preparation of agrochemicals and functional materials due to its stable heterocyclic framework. The carboxylic acid group allows for easy derivatization, making it valuable in medicinal chemistry for creating amides, esters, and other functional derivatives.
