Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(4-(tert-butyl)phenyl)-5-chloro-1-(3-chlorobenzyl)-6-oxo-1,6-dihydropyridine-3-carboxamide.
CATO supplies N-(4-(tert-butyl)phenyl)-5-chloro-1-(3-chlorobenzyl)-6-oxo-1,6-dihydropyridine-3-carboxamide (CAS 400088-59-7), a certified reference material (molecular formula C23H22Cl2N2O2, MW 429.34 g/mol) for analytical method development and quality control.
N-(4-(tert-butyl)phenyl)-5-chloro-1-(3-chlorobenzyl)-6-oxo-1,6-dihydropyridine-3-carboxamide (C23H22Cl2N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
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.
