Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
4-Bromo-2-fluoro-6-iodobenzoic acid (CAS 1936243-93-4), molecular formula C7H3BrFIO2 and molecular weight 344.90 g/mol, is a CATO reference standard with documented purity and traceability.
4-Bromo-2-fluoro-6-iodobenzoic acid (C7H3BrFIO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine/iodine substitution, an aromatic ring system. 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).
As a certified reference material (CRM), 4-Bromo-2-fluoro-6-iodobenzoic 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.
