4-(4-(Benzyloxy)-2-methylbenzoyl)-5-(4-ethoxy-3-methoxyphenyl)-3-hydroxy-1-(2-methoxyethyl)-1H-pyrrol-2(5H)-one (CAS 488734-39-0), molecular formula C31H33NO7 and molecular weight 531.60 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-(4-(Benzyloxy)-2-methylbenzoyl)-5-(4-ethoxy-3-methoxyphenyl)-3-hydroxy-1-(2-methoxyethyl)-1H-pyrrol-2(5H)-one (C31H33NO7) is characterized by a nitrogen-containing heterocyclic scaffold, 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 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.
