Chemical Structure
Description
Ethyl (3E)-2-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]sulfanyl}-3-(methoxyimino)propanoate (C12H12ClF3N2O3S) contains a nitrogen-containing heterocyclic scaffold, 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.
CATO supplies Ethyl (3E)-2-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]sulfanyl}-3-(methoxyimino)propanoate (CAS 338422-92-7), a certified reference material (molecular formula C12H12ClF3N2O3S, MW 356.75 g/mol) for analytical method development and quality control.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
