Chemical Structure
Description
2-Bromo-6-fluoro-3-nitrobenzonitrile (CAS 1807209-03-5) is a high-purity analytical reference standard with the molecular formula C7H2BrFN2O2 and a molecular weight of 245.01 g/mol.
2-Bromo-6-fluoro-3-nitrobenzonitrile (C7H2BrFN2O2) contains an amide group, 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).
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-Bromo-6-fluoro-3-nitrobenzonitrile 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.
