Chemical Structure
Description
3-bromo-4-nitro-1,2-thiazole (C3HBrN2O2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine 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.
