DIHYDRO-BETA-IONONE Usage And Synthesis

Chemical Properties

Dihydro-β-ionone has a woody, methylionone odor.

Uses

4-(2,6,6-Trimethyl-1-cyclohexen-1-yl)-2-butanone is a useful synthetic intermediate. It is a reagent used to prepare moverastin derivatives, an inhibitor of tumor cell migration. It can also be used in preparation of substituted alkene derivatives capable of releasing fragrant compounds.

Definition

ChEBI: A methyl ketone in which the keto group is attached to a 2-(2,6,6-trimethylcyclohex-1-en-1-yl)ethyl group.
