3-Methoxyphenyl 6-bromo-2-oxo-2H-chromene-3-carboxylate (CAS 324066-42-4), molecular formula C17H11BrO5 and molecular weight 375.17 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Methoxyphenyl 6-bromo-2-oxo-2H-chromene-3-carboxylate (C17H11BrO5) is characterized by a flavonoid core, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
