Chemical Structure

2-Bromo-3-cyano-6-(difluoromethyl)benzoic acid CAS 1805487-31-3 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.

2-Bromo-3-cyano-6-(difluoromethyl)benzoic acid (CAS 1805487-31-3) is a high-purity analytical reference standard with the molecular formula C9H4BrF2NO2 and a molecular weight of 276.03 g/mol.

2-Bromo-3-cyano-6-(difluoromethyl)benzoic acid (C9H4BrF2NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. 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).

As a certified reference material (CRM), 2-Bromo-3-cyano-6-(difluoromethyl)benzoic 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.
