N-(2,4-Difluorophenyl)-6-oxo-1-{[3-(trifluoromethyl)phenyl]methyl}-1,6-dihydropyridine-3-carboxamide (CAS 338783-71-4) is a high-purity analytical reference standard with the molecular formula C20H13F5N2O2 and a molecular weight of 408.32 g/mol.
The molecular framework of N-(2,4-Difluorophenyl)-6-oxo-1-{[3-(trifluoromethyl)phenyl]methyl}-1,6-dihydropyridine-3-carboxamide (C20H13F5N2O2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
