Chemical Structure
Description
3,3’,4,4’,5,5’-Hexafluoro-1,1’-biphenyl (CAS 505058-38-8), molecular formula C12H4F6 and molecular weight 262.15 g/mol, is a CATO reference standard with documented purity and traceability.
3,3’,4,4’,5,5’-Hexafluoro-1,1’-biphenyl (C12H4F6) contains fluorine 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), 3,3’,4,4’,5,5’-Hexafluoro-1,1’-biphenyl 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.
