Chemical Structure
Description
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.
CATO supplies Sodium dithiosulfatoaurate (CAS 10233-88-2), a certified reference material (molecular formula AuO6S4Na, MW 444.19 g/mol) for analytical method development and quality control.
Sodium dithiosulfatoaurate (AuO6S4Na) 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.
