Chemical Structure
Description
5-Bromo-2,6-dimethoxypyridine-3-boronic acid (C7H9BBrNO4) contains an amide 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.
5-Bromo-2,6-dimethoxypyridine-3-boronic acid (CAS 2121513-61-7) is a high-purity analytical reference standard with the molecular formula C7H9BBrNO4 and a molecular weight of 261.87 g/mol.
