6-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl](methyl)amino}-2-(4-chlorophenyl)-5H,6H,7H,7aH-pyrrolo[3,4-e][1,3]thiazine-5,7-dione (CAS 337920-07-7) is a high-purity analytical reference standard with the molecular formula C19H11Cl2F3N4O2S and a molecular weight of 487.28 g/mol.
6-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl](methyl)amino}-2-(4-chlorophenyl)-5H,6H,7H,7aH-pyrrolo[3,4-e][1,3]thiazine-5,7-dione (C19H11Cl2F3N4O2S) contains a steroid 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
