Chemical Structure

(3-Methoxyphenyl)methanesulfonyl chloride CAS 163295-76-9 chemical structure

Description

(3-Methoxyphenyl)methanesulfonyl chloride (C8H9ClO3S) contains a sulfone group, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
