Chemical Structure

Sodium tetrachloroaurate CAS 15189-51-2 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 tetrachloroaurate.

Sodium tetrachloroaurate (CAS 15189-51-2), molecular formula AuCl4Na and molecular weight 361.77 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Sodium tetrachloroaurate (AuCl4Na) is characterized by a salt form, chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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 Sodium tetrachloroaurate 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.
