Used primarily in research settings as an intermediate for synthesizing biologically active compounds, particularly in the development of potential antimicrobial and antifungal agents. Its hydrazine functionality allows it to participate in condensation reactions, forming hydrazone derivatives that are of interest in medicinal chemistry. It has also been explored in the design of enzyme inhibitors due to the sulfonamide group, which is commonly associated with inhibition of carbonic anhydrase and other metalloenzymes. Due to its reactivity and structural features, it serves as a building block in heterocyclic synthesis, especially for creating fused ring systems with pharmacological potential. Handling requires caution due to the presence of hydrazine, which can be toxic and unstable.
