Used primarily as an intermediate in organic synthesis, especially in the preparation of heterocyclic compounds. It plays a key role in the synthesis of pyridazine and triazole derivatives, which are important scaffolds in pharmaceuticals. Commonly employed in the development of medicinal agents, including antimicrobial, anti-inflammatory, and antitumor compounds. Also utilized in coordination chemistry as a ligand precursor for metal complexes with catalytic or biological activity. Its hydrazine functionality allows for facile derivatization, making it valuable in drug discovery and materials science.
