Chemical Structure
Description
The molecular framework of 1,2-Dibromo-4-difluoromethoxy-5-iodobenzene (C7H3Br2F2IO) is characterized by a hydroxyl group, an ether linkage, fluorine/bromine/iodine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
1,2-Dibromo-4-difluoromethoxy-5-iodobenzene (CAS 1803782-36-6), molecular formula C7H3Br2F2IO and molecular weight 427.81 g/mol, is a CATO reference standard with documented purity and traceability.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
