Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(4-methoxybenzyl)-2-((6-oxo-1-phenyl-4-(trifluoromethyl)-1,6-dihydropyrimidin-2-yl)thio)acetamide.
N-(4-methoxybenzyl)-2-((6-oxo-1-phenyl-4-(trifluoromethyl)-1,6-dihydropyrimidin-2-yl)thio)acetamide (CAS 866049-83-4) is a high-purity analytical reference standard with the molecular formula C21H18F3N3O3S and a molecular weight of 449.45 g/mol.
The molecular framework of N-(4-methoxybenzyl)-2-((6-oxo-1-phenyl-4-(trifluoromethyl)-1,6-dihydropyrimidin-2-yl)thio)acetamide (C21H18F3N3O3S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
