5-((4-((2-(4-Methoxyphenyl)-2-oxoethoxy)carbonyl)phenyl)amino)-5-oxopentanoic acid (CAS 774557-91-4) is a high-purity analytical reference standard with the molecular formula C21H21NO7 and a molecular weight of 399.39 g/mol.
The molecular framework of 5-((4-((2-(4-Methoxyphenyl)-2-oxoethoxy)carbonyl)phenyl)amino)-5-oxopentanoic acid (C21H21NO7) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
