Chemical Structure
Description
CATO supplies N-(2,4-Dichlorophenyl)-3-(dimethylamino)-4-(4-phenoxyphenyl)-1H-pyrazole-1-carboxamide (CAS 321553-16-6), a certified reference material (molecular formula C24H20Cl2N4O2, MW 467.35 g/mol) for analytical method development and quality control.
N-(2,4-Dichlorophenyl)-3-(dimethylamino)-4-(4-phenoxyphenyl)-1H-pyrazole-1-carboxamide (C24H20Cl2N4O2) 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, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
