4-Chlorochalcone Chemical Properties, Uses, Production

Uses

4-Chlorochalcone belongs to the ketone derivative class and can be used as a pharmaceutical synthesis intermediate.

Uses

4-Chlorochalcone is a chalcone derivative. Its crystals exhibit monoclinic system with space group P21/c. It can undergo conjugate addition reaction with pyrrole in the presence of AlKIT-5 (mesoporous 3D aluminosilicate catalyst) to form the corresponding C2-alkylated pyrrole derivatives.

Definition

ChEBI: A member of the class of chalcones that is trans-chalcone substituted by a chloro group at position 4.

Synthesis Reference(s)
