Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of antitubercular and antifungal agents. Serves as a ligand in coordination chemistry for forming metal complexes with catalytic activity. Employed in the preparation of heterocyclic compounds and pyridine-based derivatives for agrochemicals and dyes. Also utilized in research for developing fluorescent probes and sensors due to its ability to form Schiff bases with amines.
