Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other biologically active molecules. Its hydrazine functionality allows for coupling reactions with carbonyl compounds, enabling the formation of hydrazones that serve as building blocks in drug discovery. Commonly employed in the preparation of heterocyclic systems such as pyrazoles and triazoles, which are prevalent in medicinal chemistry. Also utilized in agrochemical research for designing novel active ingredients due to its ability to enhance binding affinity and selectivity in target molecules.
