Chemical Structure

2-(2,6-Dichlorophenoxy)acetyl chloride CAS 20143-46-8 chemical structure

Description

The occurrence of 2-(2,6-Dichlorophenoxy)acetyl chloride is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-(2,6-Dichlorophenoxy)acetyl chloride (CAS 20143-46-8) is a high-purity analytical reference standard with the molecular formula C8H5Cl3O2 and a molecular weight of 239.48 g/mol.

Based on its molecular formula C8H5Cl3O2, 2-(2,6-Dichlorophenoxy)acetyl chloride contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 239.48 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
