5-Methoxy-2'-(pyrrolidine-3-carbonyl)-[1,1'-biphenyl]-3-carboxylic acid (CAS 1262006-40-5), molecular formula C19H19NO4 and molecular weight 325.36 g/mol, is a CATO reference standard with documented purity and traceability.
5-Methoxy-2'-(pyrrolidine-3-carbonyl)-[1,1'-biphenyl]-3-carboxylic acid (C19H19NO4) 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.
