Chemical Structure
Description
3-((4-Chlorophenyl)thio)-N-((dimethylamino)methylene)-5-(trifluoromethyl)picolinamide (C16H13ClF3N3OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, 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; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
3-((4-Chlorophenyl)thio)-N-((dimethylamino)methylene)-5-(trifluoromethyl)picolinamide (CAS 338406-91-0), molecular formula C16H13ClF3N3OS and molecular weight 387.81 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
