Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(2,4-Dichlorophenyl)-2-oxo-1-{[4-(trifluoromethyl)phenyl]methyl}-1,2-dihydropyridine-3-carboxamide.
N-(2,4-Dichlorophenyl)-2-oxo-1-{[4-(trifluoromethyl)phenyl]methyl}-1,2-dihydropyridine-3-carboxamide (CAS 338782-19-7) is a high-purity analytical reference standard with the molecular formula C20H13Cl2F3N2O2 and a molecular weight of 441.23 g/mol.
Structurally, N-(2,4-Dichlorophenyl)-2-oxo-1-{[4-(trifluoromethyl)phenyl]methyl}-1,2-dihydropyridine-3-carboxamide (C20H13Cl2F3N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 441.23 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
