Chemical Structure
Description
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, 3-Bromo-5-chloro-2-methoxyphenylboronic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 265.30 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).
CATO supplies 3-Bromo-5-chloro-2-methoxyphenylboronic acid (CAS 2096341-68-1), a certified reference material (molecular formula C7H7BBrClO3, MW 265.30 g/mol) for analytical method development and quality control.
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
