Chemical Structure
Description
4-Bromo-2-phenylquinoline (CAS 5427-93-0), molecular formula C15H10BrN and molecular weight 284.15 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution, 4-Bromo-2-phenylquinoline is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 284.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
