Chemical Structure
Description
2-Bromo-4-methoxyphenylboronic acid (C7H8BBrO3) contains 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.
2-Bromo-4-methoxyphenylboronic acid (CAS 1879166-84-3), molecular formula C7H8BBrO3 and molecular weight 230.85 g/mol, is a CATO reference standard with documented purity and traceability.
