Chemical Structure

Magnesium thiosulfate hexahydrate CAS 13446-30-5 chemical structure

Description

The occurrence of Magnesium thiosulfate hexahydrate is closely related to a sulfone group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Magnesium thiosulfate hexahydrate (CAS 13446-30-5), molecular formula H2O3S2MgH2O and molecular weight 156.45 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Magnesium thiosulfate hexahydrate (H2O3S2MgH2O) contains a sulfone group. The molecule exhibits a degree of unsaturation (DBE) of 0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 156.45 g/mol, it falls into the medium-molecular-weight range.

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), Magnesium thiosulfate hexahydrate 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.
