Description
Compared with other compounds in its class, the molecular weight of 391.84 g/mol gives 4-[(E)-2-(2-Chlorophenyl)ethenyl]-6-(trifluoromethyl)-2H,3H-thieno[3,2-c]quinoline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-[(E)-2-(2-Chlorophenyl)ethenyl]-6-(trifluoromethyl)-2H,3H-thieno[3,2-c]quinoline (CAS 865658-33-9), molecular formula C20H13ClF3NS and molecular weight 391.84 g/mol, is a CATO reference standard with documented purity and traceability.
4-[(E)-2-(2-Chlorophenyl)ethenyl]-6-(trifluoromethyl)-2H,3H-thieno[3,2-c]quinoline (C20H13ClF3NS) 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 4-[(E)-2-(2-Chlorophenyl)ethenyl]-6-(trifluoromethyl)-2H,3H-thieno[3,2-c]quinoline 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.
