It is used as a solvent and as an intermediate for syntheses. Its industrial importance is low. It is produced by base-catalyzed aldol condensation of 2-butanone with acetaldehyde, forming , which is dehydrated to 3-methyl-3-penten-2-one over an acid catalyst, followed by hydrogenation over a palladium catalyst.y hydrogenation over a palladium catalyst.
