Chemical Structure
Description
CATO manufactures (6-Bromo-2,3-difluoro-4-methoxyphenyl)boronic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
CATO supplies (6-Bromo-2,3-difluoro-4-methoxyphenyl)boronic acid (CAS 1704080-27-2), a certified reference material (molecular formula C7H6BBrF2O3, MW 266.83 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, (6-Bromo-2,3-difluoro-4-methoxyphenyl)boronic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 266.83 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
