Methyl 4-{[(1E)-2-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]sulfanyl}-3-ethoxy-3-oxoprop-1-en-1-yl]amino}benzoate (CAS 338966-74-8), molecular formula C19H16ClF3N2O4S and molecular weight 460.85 g/mol, is a CATO reference standard with documented purity and traceability.
Methyl 4-{[(1E)-2-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]sulfanyl}-3-ethoxy-3-oxoprop-1-en-1-yl]amino}benzoate (C19H16ClF3N2O4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
