Chemical Structure

Sodium tetrachlorogold(III)ate dihydrate CAS 13874-02-7 chemical structure

Description

Sodium tetrachlorogold(III)ate dihydrate (AuCl4NaH2O) contains a salt form, 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.

Sodium tetrachlorogold(III)ate dihydrate (CAS 13874-02-7), molecular formula AuCl4NaH2O and molecular weight 379.78 g/mol, is a CATO reference standard with documented purity and traceability.

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.

As a certified reference material (CRM), Sodium tetrachlorogold(III)ate dihydrate 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.
