Chemical Structure
Description
4-Bromo-1-(trifluoromethoxy)-2-(trifluoromethyl)benzene (CAS 933674-89-6), molecular formula C8H3BrF6O and molecular weight 309.00 g/mol, is a CATO reference standard with documented purity and traceability.
4-Bromo-1-(trifluoromethoxy)-2-(trifluoromethyl)benzene (C8H3BrF6O) contains a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; 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-Bromo-1-(trifluoromethoxy)-2-(trifluoromethyl)benzene 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.
