Used as an intermediate in organic synthesis, particularly in the preparation of heterocyclic compounds with potential biological activity. It serves as a building block in the development of pharmaceuticals, including antimicrobial and anti-inflammatory agents. Its hydrazide functionality allows for condensation reactions to form hydrazones, which are valuable in medicinal chemistry and drug design. Also employed in the synthesis of fluorescent probes and sensors due to its ability to coordinate with metal ions and participate in intramolecular charge transfer processes.
