Chemical Structure
Description
Sodium 4-hydrazinylbenzene-1-sulfonate (C6H7N2O3SNa) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Sodium 4-hydrazinylbenzene-1-sulfonate (CAS 52532-33-9), molecular formula C6H7N2O3SNa and molecular weight 210.18 g/mol, is a CATO reference standard with documented purity and traceability.
