Used as an intermediate in the synthesis of heterocyclic compounds, particularly in the preparation of pyrazoles and other nitrogen-containing rings. It plays a role in pharmaceutical manufacturing, especially in the development of antitubercular and antiviral agents. Also utilized in the production of agrochemicals and as a building block in the design of bioactive molecules due to its ability to form stable hydrazone derivatives. Its reactivity makes it valuable in condensation reactions for creating functionalized hydrazide structures.
