Chemical Structure

2-Bromo-6-(difluoromethyl)pyridine-3,4-diol CAS 1805282-64-7 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.

CATO supplies 2-Bromo-6-(difluoromethyl)pyridine-3,4-diol (CAS 1805282-64-7), a certified reference material (molecular formula C6H4BrF2NO2, MW 240.00 g/mol) for analytical method development and quality control.

2-Bromo-6-(difluoromethyl)pyridine-3,4-diol (C6H4BrF2NO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/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).

As a certified reference material (CRM), 2-Bromo-6-(difluoromethyl)pyridine-3,4-diol 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.
