Chemical Structure
Description
The molecular framework of N-(2,4-dichloro-5-isopropoxyphenyl)-2-((2-oxo-2-((3-(trifluoromethyl)phenyl)amino)ethyl)sulfonyl)acetamide (C20H19Cl2F3N2O5S) 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
