Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
Ethyl 2-fluoro-2-methyl-3-oxo-3-phenylpropanoate (CAS 193482-31-4), molecular formula C12H13FO3 and molecular weight 224.23 g/mol, is a CATO reference standard with documented purity and traceability.
Ethyl 2-fluoro-2-methyl-3-oxo-3-phenylpropanoate (C12H13FO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. It is notably hygroscopic, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), Ethyl 2-fluoro-2-methyl-3-oxo-3-phenylpropanoate 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.
