Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the preparation of anticonvulsant and antimicrobial agents, including antivirals and antifungals. It participates in cyclization reactions to form heterocyclic compounds with biological activity. Commonly employed in medicinal chemistry for developing compounds targeting central nervous system disorders. Also utilized in the design of enzyme inhibitors due to its ability to coordinate with active site metals in certain proteins. Its hydrazide group allows for easy derivatization, making it valuable in creating libraries of bioactive molecules for drug discovery. Additionally, it is used in the synthesis of ligands for transition metal complexes in materials science and catalysis.
