1-(4-Methoxyphenyl)-2-(4-nitrophenyl)ethanone (CAS 20765-22-4), molecular formula C15H13NO4 and molecular weight 271.27 g/mol, is a CATO reference standard with documented purity and traceability.
1-(4-Methoxyphenyl)-2-(4-nitrophenyl)ethanone (C15H13NO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
