Chemical Structure
Description
The occurrence of Rhodium(III) sulfate solution is closely related to a sulfone group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Rhodium(III) sulfate solution (CAS 10489-46-0), a certified reference material (molecular formula RhO4S, MW 198.97 g/mol) for analytical method development and quality control.
Structurally, Rhodium(III) sulfate solution (RhO4S) contains a sulfone group. The molecule exhibits a degree of unsaturation (DBE) of 0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 198.97 g/mol, it falls into the medium-molecular-weight range.
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
