Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 268.18 g/mol gives Ethyl 2,2-Difluoro-2-[4-(trifluoromethyl)phenyl]acetate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Ethyl 2,2-Difluoro-2-[4-(trifluoromethyl)phenyl]acetate (CAS 73789-96-5), a certified reference material (molecular formula C11H9F5O2, MW 268.18 g/mol) for analytical method development and quality control.
Ethyl 2,2-Difluoro-2-[4-(trifluoromethyl)phenyl]acetate (C11H9F5O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), Ethyl 2,2-Difluoro-2-[4-(trifluoromethyl)phenyl]acetate 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.
