Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 1,5-Dichloro-2-fluoro-4-(trifluoromethoxy)benzene (CAS 1803820-70-3), a certified reference material (molecular formula C7H2Cl2F4O, MW 248.99 g/mol) for analytical method development and quality control.
1,5-Dichloro-2-fluoro-4-(trifluoromethoxy)benzene (C7H2Cl2F4O) contains a hydroxyl group, an ether linkage, fluorine/chlorine 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.
As a certified reference material (CRM), 1,5-Dichloro-2-fluoro-4-(trifluoromethoxy)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.
