Chemical Structure
Description
4-Bromo-5-fluoro-2-methylphenylboronic acid (C7H7BBrFO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/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.
4-Bromo-5-fluoro-2-methylphenylboronic acid (CAS 1646842-34-3) is a high-purity analytical reference standard with the molecular formula C7H7BBrFO2 and a molecular weight of 232.84 g/mol.
