2-((4-Chloro-3-(trifluoromethyl)phenyl)amino)-2-oxoethyl 2-(methylthio)nicotinate (CAS 438596-96-4) is a high-purity analytical reference standard with the molecular formula C16H12ClF3N2O3S and a molecular weight of 404.79 g/mol.
The molecular framework of 2-((4-Chloro-3-(trifluoromethyl)phenyl)amino)-2-oxoethyl 2-(methylthio)nicotinate (C16H12ClF3N2O3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures 2-((4-Chloro-3-(trifluoromethyl)phenyl)amino)-2-oxoethyl 2-(methylthio)nicotinate 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.
