Chemical Structure
Description
Based on its molecular formula C13H12Cl4N3O3F6P, 1,1,3,3-Tetramethyl-2-(4,5,6,7-tetrachloro-1,3-dioxoisoindolin-2-yl)isouronium hexafluorophosphate(V) contains a nitrogen-containing heterocyclic scaffold, an amide group, a phosphonate group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 545.02 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).
