CATO supplies ethyl 4-chloro-2-(methylthio)-8-(trifluoromethyl)quinoline-3-carboxylate (CAS 662138-34-3), a certified reference material (molecular formula C14H11ClF3NO2S, MW 349.76 g/mol) for analytical method development and quality control.
ethyl 4-chloro-2-(methylthio)-8-(trifluoromethyl)quinoline-3-carboxylate (C14H11ClF3NO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
