Chemical Structure
Description
The occurrence of Ethyl 2,2-difluoro-2-phenoxyacetate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Ethyl 2,2-difluoro-2-phenoxyacetate (CAS 338791-95-0), a certified reference material (molecular formula C10H10F2O3, MW 216.18 g/mol) for analytical method development and quality control.
Based on its molecular formula C10H10F2O3, Ethyl 2,2-difluoro-2-phenoxyacetate contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 216.18 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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-phenoxyacetate 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.
