3'-Bromo-3-fluoro-4-(trifluoromethoxy)-1,1'-biphenyl (CAS 1443341-93-2), molecular formula C13H7BrF4O and molecular weight 335.09 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C13H7BrF4O, 3'-Bromo-3-fluoro-4-(trifluoromethoxy)-1,1'-biphenyl contains a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 335.09 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
