Chemical Structure
Description
The occurrence of 1,5-Dichloro-2-iodo-3-methoxybenzene is closely related to a hydroxyl group, an ether linkage, chlorine/iodine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1,5-Dichloro-2-iodo-3-methoxybenzene (CAS 1271523-34-2) is a high-purity analytical reference standard with the molecular formula C7H5Cl2IO and a molecular weight of 302.92 g/mol.
Owing to a hydroxyl group, an ether linkage, chlorine/iodine substitution, an aromatic ring system, 1,5-Dichloro-2-iodo-3-methoxybenzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 302.92 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
