Sodium 2,5-bis(methoxycarbonyl)benzenesulfonate CAS 31314-30-4

Description

Compared with other compounds in its class, the molecular weight of 296.23 g/mol gives Sodium 2,5-bis(methoxycarbonyl)benzenesulfonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Sodium 2,5-bis(methoxycarbonyl)benzenesulfonate (CAS 31314-30-4), molecular formula C10H9O7SNa and molecular weight 296.23 g/mol, is a CATO reference standard with documented purity and traceability.

Sodium 2,5-bis(methoxycarbonyl)benzenesulfonate (C10H9O7SNa) contains 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 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.

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.
