4-Chloro-2,5-dimethoxyphenol CAS 18211-01-3

Description

The occurrence of 4-Chloro-2,5-dimethoxyphenol 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.

4-Chloro-2,5-dimethoxyphenol (CAS 18211-01-3), molecular formula C8H9ClO3 and molecular weight 188.61 g/mol, is a CATO reference standard with documented purity and traceability.

4-Chloro-2,5-dimethoxyphenol (C8H9ClO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
