1-Benzyl-N-(3-methoxyphenyl)-2,6-dioxo-1,2,3,6-tetrahydropyrimidine-4-carboxamide (CAS 338412-64-9) is a high-purity analytical reference standard with the molecular formula C19H17N3O4 and a molecular weight of 351.36 g/mol.
The molecular framework of 1-Benzyl-N-(3-methoxyphenyl)-2,6-dioxo-1,2,3,6-tetrahydropyrimidine-4-carboxamide (C19H17N3O4) 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
