Description
Compared with other compounds in its class, the molecular weight of 273.02 g/mol gives 3-Fluoro-5-(trifluoromethoxy)benzyl bromide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-Fluoro-5-(trifluoromethoxy)benzyl bromide (CAS 86256-51-1), a certified reference material (molecular formula C8H5BrF4O, MW 273.02 g/mol) for analytical method development and quality control.
3-Fluoro-5-(trifluoromethoxy)benzyl bromide (C8H5BrF4O) 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), 3-Fluoro-5-(trifluoromethoxy)benzyl bromide 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.
