Chemical Structure
Description
The occurrence of (4-Bromo-3-fluorophenyl)phenylmethanone is closely related to a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(4-Bromo-3-fluorophenyl)phenylmethanone (CAS 1196395-22-8), molecular formula C13H8BrFO and molecular weight 279.10 g/mol, is a CATO reference standard with documented purity and traceability.
(4-Bromo-3-fluorophenyl)phenylmethanone (C13H8BrFO) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
