The occurrence of 4-Bromo-2-chloro-6-iodophenol is closely related to a hydroxyl group, an ether linkage, chlorine/bromine/iodine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Bromo-2-chloro-6-iodophenol (CAS 858855-18-2), molecular formula C6H3BrClIO and molecular weight 333.35 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C6H3BrClIO, 4-Bromo-2-chloro-6-iodophenol contains a hydroxyl group, an ether linkage, chlorine/bromine/iodine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 333.35 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).
