Chemical Structure
Description
The occurrence of N-(2,4-dichloro-5-isopropoxyphenyl)-2-((2-oxo-2-((3-(trifluoromethyl)phenyl)amino)ethyl)thio)acetamide is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies N-(2,4-dichloro-5-isopropoxyphenyl)-2-((2-oxo-2-((3-(trifluoromethyl)phenyl)amino)ethyl)thio)acetamide (CAS 341964-74-7), a certified reference material (molecular formula C20H19Cl2F3N2O3S, MW 495.34 g/mol) for analytical method development and quality control.
N-(2,4-dichloro-5-isopropoxyphenyl)-2-((2-oxo-2-((3-(trifluoromethyl)phenyl)amino)ethyl)thio)acetamide (C20H19Cl2F3N2O3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/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.
