Chemical Structure

4,5-Difluoro-2-methoxybenzyl bromide CAS 886499-64-5 chemical structure

Description

The occurrence of 4,5-Difluoro-2-methoxybenzyl bromide is closely related to a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 4,5-Difluoro-2-methoxybenzyl bromide (CAS 886499-64-5), a certified reference material (molecular formula C8H7BrF2O, MW 237.04 g/mol) for analytical method development and quality control.

Owing to a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system, 4,5-Difluoro-2-methoxybenzyl bromide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 237.04 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
