Chemical Structure

Sodium monothiosulfatoaurate CAS 38295-16-8 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Sodium monothiosulfatoaurate.

Sodium monothiosulfatoaurate (CAS 38295-16-8) is a high-purity analytical reference standard with the molecular formula AuO3S2Na and a molecular weight of 332.08 g/mol.

Sodium monothiosulfatoaurate (AuO3S2Na) contains a sulfone group. It is notably hygroscopic; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
