Chemical Structure
Description
The occurrence of 2-[N-(2,4-Dichloro-5-methoxyphenyl)4-fluorobenzenesulfonamido]-N-[3-(trifluoromethyl)phenyl]acetamide is closely related to a flavonoid 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.
2-[N-(2,4-Dichloro-5-methoxyphenyl)4-fluorobenzenesulfonamido]-N-[3-(trifluoromethyl)phenyl]acetamide (CAS 338967-36-5), molecular formula C22H16Cl2F4N2O4S and molecular weight 551.34 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-[N-(2,4-Dichloro-5-methoxyphenyl)4-fluorobenzenesulfonamido]-N-[3-(trifluoromethyl)phenyl]acetamide (C22H16Cl2F4N2O4S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
