Chemical Structure
Description
2-(Methylthio)-8-nitro-6-(trifluoromethyl)-4H-benzo[e][1,3]thiazin-4-one (C10H5F3N2O3S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine 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.
2-(Methylthio)-8-nitro-6-(trifluoromethyl)-4H-benzo[e][1,3]thiazin-4-one (CAS 1344087-73-5), molecular formula C10H5F3N2O3S2 and molecular weight 322.28 g/mol, is a CATO reference standard with documented purity and traceability.
