Chemical Structure

Sodium 2-Hydroxypropanesulfonate CAS 1561-96-2 chemical structure

Description

As a certified reference material (CRM), Sodium 2-Hydroxypropanesulfonate 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.

Sodium 2-Hydroxypropanesulfonate (CAS 1561-96-2), molecular formula C3H7O4SNa and molecular weight 162.13 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a sulfone group, a carboxylic acid group, an ether linkage, Sodium 2-Hydroxypropanesulfonate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 162.13 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.
