Chemical Structure

Sodium Sulfide CAS 1313-82-2 chemical structure

Description

Owing to sulfur-containing functionality, Sodium Sulfide is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 78.04 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

Sodium Sulfide (CAS 1313-82-2), molecular formula Na2S and molecular weight 78.04 g/mol, is a CATO reference standard with documented purity and traceability.

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 Sulfide 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.
