Chemical Structure
Description
The molecular framework of (E)-Ethyl 3-(2-ethoxy-5-nitrophenyl)-2,2-difluoro-3-(2-((2-(trifluoromethyl)phenyl)sulfonyl)hydrazono)propanoate (C20H18F5N3O7S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
