Chemical Structure
Description
6,7-Dichloro-3-(3-chloro-5-(trifluoromethyl)pyridin-2-yl)quinoxalin-2(1H)-one (C14H5Cl3F3N3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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).
