477889-01-3 5,5-bis[2-(4-bromophenyl)-2-oxoethyl]-1,3-dimethyl-2,4,6(1H,3H,5H)-pyrimidinetrione KS-000034NP (CAS 477889-01-3) is a high-purity analytical reference standard with the molecular formula C22H18Br2N2O5 and a molecular weight of 550.20 g/mol.
The molecular framework of 477889-01-3 5,5-bis[2-(4-bromophenyl)-2-oxoethyl]-1,3-dimethyl-2,4,6(1H,3H,5H)-pyrimidinetrione KS-000034NP (C22H18Br2N2O5) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. 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.
