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-Methyl-2-oxo-N-phenyl-1-{[4-(trifluoromethyl)phenyl]methyl}-1,2-dihydropyridine-3-carboxamide.
CATO supplies N-Methyl-2-oxo-N-phenyl-1-{[4-(trifluoromethyl)phenyl]methyl}-1,2-dihydropyridine-3-carboxamide (CAS 338781-63-8), a certified reference material (molecular formula C21H17F3N2O2, MW 386.37 g/mol) for analytical method development and quality control.
Based on its molecular formula C21H17F3N2O2, N-Methyl-2-oxo-N-phenyl-1-{[4-(trifluoromethyl)phenyl]methyl}-1,2-dihydropyridine-3-carboxamide contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 386.37 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
