Chemical Structure
Description
Dibromobis(2-(2'-pyridyl)quinoline)rhodium(III) bromide (CAS 125955-74-0) is a high-purity analytical reference standard with the molecular formula C28H20Br2N4RhBr and a molecular weight of 755.12 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution, Dibromobis(2-(2'-pyridyl)quinoline)rhodium(III) bromide is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 755.12 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
