Chemical Structure
Description
Based on its molecular formula C7H5ClF2O, 2,6-Difluoro-1,5-Cyclohexadiene-1-Carbonyl Chloride contains a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 178.56 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
