Chemical Structure
Description
(4-bromopyridin-3-yl)boronic acid hydrobromide (C5H5BBrNO2HBr) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. 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.
