Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 269.95 g/mol gives 5-Bromo-1,3-dichloro-2-ethoxybenzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-Bromo-1,3-dichloro-2-ethoxybenzene (CAS 749932-70-5) is a high-purity analytical reference standard with the molecular formula C8H7BrCl2O and a molecular weight of 269.95 g/mol.
Owing to a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system, 5-Bromo-1,3-dichloro-2-ethoxybenzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 269.95 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).
