Chemical Structure
Description
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.
N-(3-Methylphenyl)-2-oxo-1-{[3-(trifluoromethyl)phenyl]methyl}-1,2-dihydropyridine-3-carboxamide (CAS 339027-85-9) is a high-purity analytical reference standard with the molecular formula C21H17F3N2O2 and a molecular weight of 386.37 g/mol.
Based on its molecular formula C21H17F3N2O2, N-(3-Methylphenyl)-2-oxo-1-{[3-(trifluoromethyl)phenyl]methyl}-1,2-dihydropyridine-3-carboxamide contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 386.37 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
