Chemical Structure

Sodium Hydrosulfide CAS 16721-80-5 chemical structure

Description

The occurrence of Sodium Hydrosulfide is closely related to sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Sodium Hydrosulfide (CAS 16721-80-5), molecular formula HSNa and molecular weight 56.06 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Sodium Hydrosulfide (HSNa) is characterized by sulfur-containing functionality. 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.

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 Hydrosulfide 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.
