Chemical Structure
Description
3-Bromo-4,5-difluoro-1H-pyrrolo[2,3-b]pyridine (C7H3BrF2N2) contains a nitrile group, fluorine/bromine substitution, an aromatic ring system. 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).
