CATO supplies 7-Bromo-6-methoxy-2-(2-nitrophenyl)quinoline-5,8-dione (CAS 61472-35-3), a certified reference material (molecular formula C16H9BrN2O5, MW 389.16 g/mol) for analytical method development and quality control.
7-Bromo-6-methoxy-2-(2-nitrophenyl)quinoline-5,8-dione (C16H9BrN2O5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
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.
