(4-Bromophenyl)[4-(trifluoromethyl)phenyl]methanone CAS 21084-23-1

Description

The occurrence of (4-Bromophenyl)[4-(trifluoromethyl)phenyl]methanone is closely related to a hydroxyl group, an ether linkage, fluorine/bromine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(4-Bromophenyl)[4-(trifluoromethyl)phenyl]methanone (CAS 21084-23-1), molecular formula C14H8BrF3O and molecular weight 329.11 g/mol, is a CATO reference standard with documented purity and traceability.

(4-Bromophenyl)[4-(trifluoromethyl)phenyl]methanone (C14H8BrF3O) contains a hydroxyl group, an ether linkage, fluorine/bromine substitution, a polycyclic aromatic 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.

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.
