Chemical Structure
Description
As a certified reference material (CRM), 4-Bromo-2-chloro-3-fluorobenzoic 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.
CATO supplies 4-Bromo-2-chloro-3-fluorobenzoic acid (CAS 1807036-03-8), a certified reference material (molecular formula C7H3BrClFO2, MW 253.45 g/mol) for analytical method development and quality control.
4-Bromo-2-chloro-3-fluorobenzoic acid (C7H3BrClFO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine/bromine 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 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).
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.
