Chemical Structure
Description
2-Fluoro-3-bromo-5-carboxyphenylboronic acid (C7H5BBrFO4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
2-Fluoro-3-bromo-5-carboxyphenylboronic acid (CAS 1452575-84-6) is a high-purity analytical reference standard with the molecular formula C7H5BBrFO4 and a molecular weight of 262.83 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-Fluoro-3-bromo-5-carboxyphenylboronic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
