Chemical Structure
Description
5-Bromo-1H-pyrrolo[2,3-b]pyridine-3-sulfonyl fluoride (C7H4BrFN2O2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
5-Bromo-1H-pyrrolo[2,3-b]pyridine-3-sulfonyl fluoride (CAS 2138133-25-0) is a high-purity analytical reference standard with the molecular formula C7H4BrFN2O2S and a molecular weight of 279.09 g/mol.
