Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 315.09 g/mol gives 2-Bromo-3,4,5-trifluorobenzophenone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Bromo-3,4,5-trifluorobenzophenone (CAS 951888-36-1), molecular formula C13H6BrF3O and molecular weight 315.09 g/mol, is a CATO reference standard with documented purity and traceability.
2-Bromo-3,4,5-trifluorobenzophenone (C13H6BrF3O) contains a hydroxyl group, an ether linkage, fluorine/bromine 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
