Chemical Structure
Description
Based on its molecular formula C11H6Cl2FNO2, 3,4-Dichloro-1-[(2-fluorophenyl)methyl]-2,5-dihydro-1h-pyrrole-2,5-dione contains a nitrogen-containing heterocyclic scaffold, an amide 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 274.08 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
