Chemical Structure

(4-Chloro-2-fluoro-6-methoxyphenyl)boronic acid CAS 1628684-10-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 204.39 g/mol gives (4-Chloro-2-fluoro-6-methoxyphenyl)boronic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(4-Chloro-2-fluoro-6-methoxyphenyl)boronic acid (CAS 1628684-10-5) is a high-purity analytical reference standard with the molecular formula C7H7BClFO3 and a molecular weight of 204.39 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, (4-Chloro-2-fluoro-6-methoxyphenyl)boronic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 204.39 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.
