Used as an intermediate in organic synthesis, particularly in the preparation of heterocyclic compounds for pharmaceuticals. It serves as a building block in the development of kinase inhibitors and antimicrobial agents. Its hydrazine and hydroxyl functional groups allow for versatile derivatization, making it valuable in medicinal chemistry for constructing pyridine-based drug candidates. Also employed in the synthesis of fluorescent probes and sensors due to its ability to form stable complexes with metal ions.
