Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 5-(4-Chlorophenyl)-2-oxo-1-{[3-(trifluoromethyl)phenyl]methyl}-1,2-dihydropyridine-3-carbonitrile is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 388.77 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
5-(4-Chlorophenyl)-2-oxo-1-{[3-(trifluoromethyl)phenyl]methyl}-1,2-dihydropyridine-3-carbonitrile (CAS 338954-80-6) is a high-purity analytical reference standard with the molecular formula C20H12ClF3N2O and a molecular weight of 388.77 g/mol.
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.
