Used primarily as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the preparation of nitrogen-containing heterocyclic drugs. It plays a role in the development of certain antiviral and antibacterial agents due to its ability to participate in ring-forming reactions. Its hydrazine functionality allows for derivatization into active pharmacophores, making it valuable in medicinal chemistry research. Additionally, it has been employed in the production of agrochemicals and specialty polymers where controlled reactivity of hydrazine derivatives is required.
