Based on its molecular formula C13H23ClO4, Rosuvastatin Impurity 86 contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 278.77 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.
