Chemical Structure

Sodium sulfite heptahydrate CAS 10102-15-5 chemical structure

Description

CATO supplies Sodium sulfite heptahydrate (CAS 10102-15-5), a certified reference material (molecular formula H2O3SNaH2O, MW 123.08 g/mol) for analytical method development and quality control.

The molecular framework of Sodium sulfite heptahydrate (H2O3SNaH2O) is characterized by a sulfone group. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

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 sulfite heptahydrate 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.
