Chemical Structure

Sodium 2- (hydroxy) (sulfonyl) methyl) benzenesulfonate CAS CATO-C3D-262161 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

Sodium 2- (hydroxy) (sulfonyl) methyl) benzenesulfonate (CAS CATO-C3D-262161) is a high-purity analytical reference standard with the molecular formula C7H6Na2O7S2 and a molecular weight of 312.23 g/mol.

Sodium 2- (hydroxy) (sulfonyl) methyl) benzenesulfonate (C7H6Na2O7S2) contains a carbohydrate-derived structure, a sulfone group. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), Sodium 2- (hydroxy) (sulfonyl) methyl) benzenesulfonate 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.
