Description
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.
5,6-Diphenyl-2-(trifluoromethyl)pyrimidin-4(1H)-one (CAS 613667-21-3) is a high-purity analytical reference standard with the molecular formula C17H11F3N2O and a molecular weight of 316.28 g/mol.
5,6-Diphenyl-2-(trifluoromethyl)pyrimidin-4(1H)-one (C17H11F3N2O) contains a steroid core, an amide group, 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).
CATO manufactures 5,6-Diphenyl-2-(trifluoromethyl)pyrimidin-4(1H)-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
