Chemical Structure
Description
The occurrence of Rhodium(III) bromide dihydrate is closely related to bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Rhodium(III) bromide dihydrate (CAS 76758-40-2), a certified reference material (molecular formula Br3RhH2O, MW 360.64 g/mol) for analytical method development and quality control.
The molecular framework of Rhodium(III) bromide dihydrate (Br3RhH2O) is characterized by bromine 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.
As a certified reference material (CRM), Rhodium(III) bromide 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.
