Chemical Structure
Description
As a certified reference material (CRM), Sodium Benzene-1,3-disulfonate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
Sodium Benzene-1,3-disulfonate (CAS 831-59-4), molecular formula C6H4O6S2Na and molecular weight 259.20 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Sodium Benzene-1,3-disulfonate (C6H4O6S2Na) contains a carbohydrate-derived structure, a sulfone group. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 259.20 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.
