Chemical Structure
Description
Ethyl (E)-4-chloro-5-(((3-hydroxypropyl)imino)methyl)-3-methylbenzofuran-2-carboxylate (C16H18ClNO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
