Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 208.21 g/mol gives Sodium 2,5-dimethylbenzenesulfonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Sodium 2,5-dimethylbenzenesulfonate (CAS 827-19-0), a certified reference material (molecular formula C8H9O3SNa, MW 208.21 g/mol) for analytical method development and quality control.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, Sodium 2,5-dimethylbenzenesulfonate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 208.21 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.
As a certified reference material (CRM), Sodium 2,5-dimethylbenzenesulfonate 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.
