Chemical Structure
Description
5-Bromo-2-iodo-3-nitrobenzoic acid (C7H3BrINO4) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine/iodine 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-2-iodo-3-nitrobenzoic acid (CAS 855749-52-9), molecular formula C7H3BrINO4 and molecular weight 371.91 g/mol, is a CATO reference standard with documented purity and traceability.
