Chemical Structure
Description
4-Bromo-1-nitroisoquinoline (C9H5BrN2O2) contains a nitrogen-containing heterocyclic scaffold, an amide 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. 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).
4-Bromo-1-nitroisoquinoline (CAS 182184-81-2) is a high-purity analytical reference standard with the molecular formula C9H5BrN2O2 and a molecular weight of 253.05 g/mol.
