Chemical Structure
Description
(3-Bromophenyl)(3,4,5-trifluorophenyl)methanone (CAS 951888-39-4), molecular formula C13H6BrF3O and molecular weight 315.09 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C13H6BrF3O, (3-Bromophenyl)(3,4,5-trifluorophenyl)methanone 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 315.09 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
