Chemical Structure
Description
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.
6-Phenyl-2-(phenylsulfanyl)-4-(trifluoromethyl)nicotinonitrile (CAS 338749-48-7), molecular formula C19H11F3N2S and molecular weight 356.36 g/mol, is a CATO reference standard with documented purity and traceability.
6-Phenyl-2-(phenylsulfanyl)-4-(trifluoromethyl)nicotinonitrile (C19H11F3N2S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 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 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.
