Chemical Structure
Description
Structurally, 5-Chloro-1-[(3,5-dimethylphenyl)methyl]-2-oxo-N-phenyl-1,2-dihydropyridine-3-carboxamide (C21H19ClN2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, 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 366.84 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO supplies 5-Chloro-1-[(3,5-dimethylphenyl)methyl]-2-oxo-N-phenyl-1,2-dihydropyridine-3-carboxamide (CAS 400087-63-0), a certified reference material (molecular formula C21H19ClN2O2, MW 366.84 g/mol) for analytical method development and quality control.
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.
