Chemical Structure

1,4-Dichlorobut-3-en-2-one CAS 15787-79-8 chemical structure

Description

1,4-Dichlorobut-3-en-2-one (C4H4Cl2O) contains a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; 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.
