Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of anti-inflammatory and antipsychotic agents. It serves as a building block in medicinal chemistry due to its ability to modulate biological activity when incorporated into larger molecules. Also employed in the preparation of agrochemicals and functional materials where aromatic heterocyclic structures enhance stability and reactivity. Its carboxylic acid group allows for easy derivatization, enabling the formation of amides, esters, and other functional derivatives for targeted applications.
