Chemical Structure

Sodium sulfate, anhydrous CAS 7757-82-6 chemical structure

Description

CATO supplies Sodium sulfate, anhydrous (CAS 7757-82-6), a certified reference material (molecular formula O4SNa, MW 119.05 g/mol) for analytical method development and quality control.

Owing to a sulfone group, Sodium sulfate, anhydrous is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 119.05 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), Sodium sulfate, anhydrous 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.
