Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 280.24 g/mol gives (2-Methoxyphenyl)(4-(trifluoromethyl)phenyl)methanone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies (2-Methoxyphenyl)(4-(trifluoromethyl)phenyl)methanone (CAS 256475-07-7), a certified reference material (molecular formula C15H11F3O2, MW 280.24 g/mol) for analytical method development and quality control.
(2-Methoxyphenyl)(4-(trifluoromethyl)phenyl)methanone (C15H11F3O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
