Used primarily as an intermediate in the synthesis of pharmaceuticals and agrochemicals. It serves as a building block in the preparation of heterocyclic compounds, particularly in the formation of indoles and pyrazoles, which are common scaffolds in drug development. Its hydrazine functionality allows it to participate in condensation reactions, especially with carbonyl compounds, enabling the construction of hydrazone derivatives that exhibit biological activity. Also employed in research settings for the development of novel organic compounds with potential antitumor, antimicrobial, or anti-inflammatory properties.
