Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Fluoro-3-(trifluoromethoxy)benzyl bromide.
CATO supplies 4-Fluoro-3-(trifluoromethoxy)benzyl bromide (CAS 86256-50-0), a certified reference material (molecular formula C8H5BrF4O, MW 273.02 g/mol) for analytical method development and quality control.
Based on its molecular formula C8H5BrF4O, 4-Fluoro-3-(trifluoromethoxy)benzyl bromide contains a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 273.02 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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-Fluoro-3-(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.
