Chemical Structure
Description
2-Fluoro-5-iodo-3-nitrobenzoic acid (CAS 1161859-57-9), molecular formula C7H3FINO4 and molecular weight 311.01 g/mol, is a CATO reference standard with documented purity and traceability.
2-Fluoro-5-iodo-3-nitrobenzoic acid (C7H3FINO4) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/iodine 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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-5-iodo-3-nitrobenzoic 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.
