Chemical Structure
Description
The occurrence of Auranofin is closely related to a sulfone group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Auranofin (CAS 34031-32-8), a certified reference material (molecular formula C14H19O9SAuC6H16P, MW 679.50 g/mol) for analytical method development and quality control.
Owing to a sulfone group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, Auranofin is typically white to off-white amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 679.50 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
CATO manufactures Auranofin under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
