Chemical Structure
Description
2-[(3,4-Dichlorophenyl)sulfanyl]-5-[3-(trifluoromethyl)phenyl]pyridine-3-carbonitrile (C19H9Cl2F3N2S) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
2-[(3,4-Dichlorophenyl)sulfanyl]-5-[3-(trifluoromethyl)phenyl]pyridine-3-carbonitrile (CAS 338964-87-7) is a high-purity analytical reference standard with the molecular formula C19H9Cl2F3N2S and a molecular weight of 425.25 g/mol.
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), 2-[(3,4-Dichlorophenyl)sulfanyl]-5-[3-(trifluoromethyl)phenyl]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.
