Description
As a certified reference material (CRM), 2,6-Difluoro-4-(trifluoromethoxy)toluene 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.
2,6-Difluoro-4-(trifluoromethoxy)toluene (CAS 1803828-47-8), molecular formula C8H5F5O and molecular weight 212.12 g/mol, is a CATO reference standard with documented purity and traceability.
2,6-Difluoro-4-(trifluoromethoxy)toluene (C8H5F5O) contains a hydroxyl group, an ether linkage, fluorine 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.
