Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 455.92 g/mol gives 4,4′-Dibromooctafluorobiphenyl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4,4′-Dibromooctafluorobiphenyl (CAS 10386-84-2), molecular formula C12Br2F8 and molecular weight 455.92 g/mol, is a CATO reference standard with documented purity and traceability.
4,4′-Dibromooctafluorobiphenyl (C12Br2F8) contains fluorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 4,4′-Dibromooctafluorobiphenyl meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
