Chemical Structure
Description
The occurrence of 3-Amino-4-hydroxy-5-nitrobenzenesulfonic acid is closely related to a carbohydrate-derived structure, an amide group, a sulfone group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Amino-4-hydroxy-5-nitrobenzenesulfonic acid (CAS 96-93-5), molecular formula C6H6N2O6S and molecular weight 234.19 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carbohydrate-derived structure, an amide group, a sulfone group, 3-Amino-4-hydroxy-5-nitrobenzenesulfonic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 234.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
