5-Chloro-N-methyl-2-oxo-N-phenyl-1-(4-(trifluoromethyl)benzyl)-1,2-dihydropyridine-3-carboxamide CAS 338977-90-5

Description

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.

5-Chloro-N-methyl-2-oxo-N-phenyl-1-(4-(trifluoromethyl)benzyl)-1,2-dihydropyridine-3-carboxamide (CAS 338977-90-5), molecular formula C21H16ClF3N2O2 and molecular weight 420.81 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 5-Chloro-N-methyl-2-oxo-N-phenyl-1-(4-(trifluoromethyl)benzyl)-1,2-dihydropyridine-3-carboxamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 420.81 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
