Chemical Structure
Description
(4-(Tert-butyl)phenyl)(3,4,5-trifluorophenyl)methanone (CAS 951888-54-3), molecular formula C17H15F3O and molecular weight 292.30 g/mol, is a CATO reference standard with documented purity and traceability.
(4-(Tert-butyl)phenyl)(3,4,5-trifluorophenyl)methanone (C17H15F3O) contains a steroid core, a hydroxyl group, an ether linkage, fluorine substitution. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
