Used primarily as a key intermediate in the synthesis of pharmaceuticals, particularly in the preparation of hydrazine-based drugs. It plays an important role in the development of certain antidepressants and antitubercular agents due to its ability to form biologically active hydrazide derivatives. Also utilized in agrochemical synthesis for creating herbicides and plant growth regulators. Its reactivity makes it valuable in organic chemistry for constructing nitrogen-containing heterocycles. Handle with care due to potential toxicity and corrosiveness.
