Chemical Structure
Description
3-Bromo-4-chloro-5,7-difluoroquinoline (C9H3BrClF2N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine/bromine substitution. Halogen substitution raises its density and boiling point; 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).
