Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of bioactive molecules with antimicrobial or anti-inflammatory properties. It serves as a building block in heterocyclic chemistry, enabling the construction of complex pyrrole-based structures found in some drug candidates. Its carboxylic acid functionality allows for easy derivatization, making it valuable in medicinal chemistry for creating amides, esters, and other functionalized compounds. Also employed in research for designing novel organic materials and ligands for metal coordination in catalysis.
