Phenyl Hydrazine hydrochloride CAS No. 59-88-1 About

Phenylhydrazine Hydrochloride (also known as Phenylhydrazinium chloride, Hydrochloride of phenylhydrazine, or Benzenediazonium hydride hydrochloride, though less commonly used) is an aromatic hydrazine salt with the molecular formula CHClN. It is the hydrochloride form of phenylhydrazine, offering improved stability and ease of handling compared to the free base. This compound appears as a crystalline solid and is widely used as a chemical intermediate in organic synthesis. It plays an important role in the preparation of pharmaceuticals, agrochemicals, dyes, and heterocyclic compounds such as indoles and pyrazoles. Additionally, it is used in analytical chemistry for the detection of carbonyl compounds through hydrazone formation and in research applications involving carbohydrate characterization and Fischer indole synthesis.
