Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 457.23 g/mol gives 1-[(2,6-Dichlorophenyl)methyl]-6-oxo-N-[4-(trifluoromethoxy)phenyl]-1,6-dihydropyridine-3-carboxamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1-[(2,6-Dichlorophenyl)methyl]-6-oxo-N-[4-(trifluoromethoxy)phenyl]-1,6-dihydropyridine-3-carboxamide (CAS 339008-64-9), a certified reference material (molecular formula C20H13Cl2F3N2O3, MW 457.23 g/mol) for analytical method development and quality control.
Structurally, 1-[(2,6-Dichlorophenyl)methyl]-6-oxo-N-[4-(trifluoromethoxy)phenyl]-1,6-dihydropyridine-3-carboxamide (C20H13Cl2F3N2O3) 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 457.23 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).
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.
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.
