Chemical Structure
Description
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.
N-(2-bromophenyl)-2-(3,4-dichlorophenyl)quinoline-4-carboxamide (CAS 332176-53-1) is a high-purity analytical reference standard with the molecular formula C22H13BrCl2N2O and a molecular weight of 472.16 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, N-(2-bromophenyl)-2-(3,4-dichlorophenyl)quinoline-4-carboxamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 472.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
