Chemical Structure
Description
6-Bromo-2-(2,4-dimethoxyphenyl)quinoline-4-carboxylic acid (CAS 351329-40-3), molecular formula C18H14BrNO4 and molecular weight 388.21 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution, 6-Bromo-2-(2,4-dimethoxyphenyl)quinoline-4-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 388.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
