Chemical Structure

Tripotassium hexachlororhodate CAS 13845-07-3 chemical structure

Description

As a certified reference material (CRM), Tripotassium hexachlororhodate 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.

Tripotassium hexachlororhodate (CAS 13845-07-3) is a high-purity analytical reference standard with the molecular formula Cl6KRhK2 and a molecular weight of 432.90 g/mol.

Owing to a salt form, chlorine substitution, Tripotassium hexachlororhodate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 432.90 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
