Used as a key intermediate in the synthesis of nitrogen-containing heterocyclic compounds, particularly in the preparation of pyridine and triazole derivatives. It serves in pharmaceutical research for developing bioactive molecules, including kinase inhibitors and antimicrobial agents. Its hydrazine functionality allows for condensation reactions, making it valuable in forming hydrazone-based sensors and coordination compounds in material science. Also applied in agrochemical synthesis for novel herbicides and plant growth regulators.
