Based on its molecular formula C11H5BrCl2O2, 4-Bromo-5-(3,4-dichlorophenyl)furan-2-carbaldehyde contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 319.97 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.
4-Bromo-5-(3,4-dichlorophenyl)furan-2-carbaldehyde (CAS 1403567-72-5), molecular formula C11H5BrCl2O2 and molecular weight 319.97 g/mol, is a CATO reference standard with documented purity and traceability.
