Compared with other compounds in its class, the molecular weight of 285.03 g/mol gives 3-(2-Bromo-4-fluorophenyl)-1,1,1-trifluoropropan-2-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-(2-Bromo-4-fluorophenyl)-1,1,1-trifluoropropan-2-one (CAS 1343587-98-3), molecular formula C9H5BrF4O and molecular weight 285.03 g/mol, is a CATO reference standard with documented purity and traceability.
3-(2-Bromo-4-fluorophenyl)-1,1,1-trifluoropropan-2-one (C9H5BrF4O) contains a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
