Chemical Structure

Sodium 3-carboxybenzenesulfonate CAS 17625-03-5 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Sodium 3-carboxybenzenesulfonate.

CATO supplies Sodium 3-carboxybenzenesulfonate (CAS 17625-03-5), a certified reference material (molecular formula C7H11O5SNa, MW 230.21 g/mol) for analytical method development and quality control.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, Sodium 3-carboxybenzenesulfonate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 230.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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-carboxybenzenesulfonate 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.
