Chemical Structure
Description
2,2-Difluoro-N-(4-fluorophenyl)-2-[3-(trifluoromethyl)phenoxy]acetamide (C15H9F6NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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.
2,2-Difluoro-N-(4-fluorophenyl)-2-[3-(trifluoromethyl)phenoxy]acetamide (CAS 338792-00-0), molecular formula C15H9F6NO2 and molecular weight 349.23 g/mol, is a CATO reference standard with documented purity and traceability.
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), 2,2-Difluoro-N-(4-fluorophenyl)-2-[3-(trifluoromethyl)phenoxy]acetamide 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.
