Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Sodium 3,4-dimethoxybenzene-1-sulfinate.
CATO supplies Sodium 3,4-dimethoxybenzene-1-sulfinate (CAS 123065-25-8), a certified reference material (molecular formula C8H9O4SNa, MW 224.21 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 3,4-dimethoxybenzene-1-sulfinate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 224.21 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 3,4-dimethoxybenzene-1-sulfinate 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.
