Used in organic synthesis as a hydrazine derivative, this compound serves as an intermediate in the preparation of heterocyclic compounds and pharmaceuticals. Its hydrazine functionality allows it to participate in condensation reactions, forming hydrazones and azoles, which are common structural motifs in bioactive molecules. It is also employed in the development of dyes and functional materials due to its ability to form stable complexes with metals. The benzenesulfonic acid component enhances solubility and stability, making it suitable for use in aqueous or polar environments during synthesis.
