Description
As a certified reference material (CRM), 3,4-Difluoro-2,2-dimethylpropiophenone 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.
3,4-Difluoro-2,2-dimethylpropiophenone (CAS 898789-74-7), molecular formula C11H12F2O and molecular weight 198.21 g/mol, is a CATO reference standard with documented purity and traceability.
3,4-Difluoro-2,2-dimethylpropiophenone (C11H12F2O) contains 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; 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).
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.
