Used as an intermediate in organic synthesis, particularly in the preparation of hydrazine-based pharmaceuticals and bioactive compounds. Its hydrazine functionality allows for coupling reactions in the development of heterocyclic systems, which are common in medicinal chemistry. Commonly employed in research settings for modifying ester and sulfonate-containing molecules to enhance solubility or reactivity. Also utilized in the synthesis of selective enzyme inhibitors and antimicrobial agents due to its ability to form stable derivatives with carbonyl and carboxyl groups.
