Chemical Structure

Ammonium tetrachloroaurate hydrate CAS 13874-04-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 374.82 g/mol gives Ammonium tetrachloroaurate hydrate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Ammonium tetrachloroaurate hydrate (CAS 13874-04-9), molecular formula AuCl4H4NH2O and molecular weight 374.82 g/mol, is a CATO reference standard with documented purity and traceability.

Ammonium tetrachloroaurate hydrate (AuCl4H4NH2O) contains chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), Ammonium tetrachloroaurate hydrate 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.
