Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Amino-1,3-benzenedissulfonic acid.
5-Amino-1,3-benzenedissulfonic acid (CAS 5294-05-3), molecular formula C6H7NO6S2 and molecular weight 253.25 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 5-Amino-1,3-benzenedissulfonic acid (C6H7NO6S2) contains a carbohydrate-derived structure, an amide group, a sulfone group. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 253.25 g/mol, it falls into the medium-molecular-weight range. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
