Description
CATO supplies 1-Chloro-2,4-difluoro-3-(trifluoromethoxy)benzene 1261811-61-3 (CAS 1261811-61-3), a certified reference material (molecular formula C7H2ClF5O, MW 232.54 g/mol) for analytical method development and quality control.
1-Chloro-2,4-difluoro-3-(trifluoromethoxy)benzene 1261811-61-3 (C7H2ClF5O) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 1-Chloro-2,4-difluoro-3-(trifluoromethoxy)benzene 1261811-61-3 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.
