4-Hydrazinobenzene-1-Sulfonamide Hydrochloride Powder CAS 17852-52-7

4-Hydrazinobenzene-1-Sulfonamide Hydrochloride is a white to off-white crystalline solid with stable chemical properties under dry and cool storage conditions. As a key aromatic hydrazine sulfonamide intermediate, it carries reactive hydrazine groups for condensation and cyclization reactions. It finds usage in building sulfonamide pharmaceutical molecules, constructing heterocyclic skeletons, custom fine chemical synthesis and making analytical reference reagents. 

The material dissolves well in polar aqueous solvents while showing poor solubility in non-polar organic reagents. Rigorous purification keeps impurities, heavy metals and residual solvents at low levels. Batch-to-batch uniformity reduces experimental variation during synthesis.

1. Serves as core building block for synthesis of sulfonamide-based pharmaceutical compounds.

2. Used to construct heterocyclic structures via hydrazine condensation and cyclization reactions.

3. Applied in laboratory custom fine chemical synthesis and medicinal chemistry research.
