Used as a key intermediate in the synthesis of heterocyclic compounds, particularly in the preparation of pyrazoles and triazoles, which are important structures in pharmaceuticals and agrochemicals. It serves as a hydrazine derivative that readily reacts with carbonyl compounds, enabling the formation of hydrazone derivatives for use in drug discovery. Commonly applied in the development of active pharmaceutical ingredients (APIs) due to its ability to introduce nitrogen-containing functional groups. Also utilized in research laboratories for the design of novel bioactive molecules and in the production of specialty chemicals requiring hydrazide functionalities.
