Chemical Structure
Description
6-(4-Chlorophenyl)-2-(phenylsulfanyl)-4-(trifluoromethyl)pyridine-3-carbonitrile (CAS 338963-44-3) is a high-purity analytical reference standard with the molecular formula C19H10ClF3N2S and a molecular weight of 390.81 g/mol.
6-(4-Chlorophenyl)-2-(phenylsulfanyl)-4-(trifluoromethyl)pyridine-3-carbonitrile (C19H10ClF3N2S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine/chlorine 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.
As a certified reference material (CRM), 6-(4-Chlorophenyl)-2-(phenylsulfanyl)-4-(trifluoromethyl)pyridine-3-carbonitrile meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
