Uses
Uses in perfumery :
DihydroBeta-Ionone is used in current and fine fragrance, in leather, rosy, red fruits, woody and lily of the valley notes.
Year of discovery :
Data not available.
Natural availability :
DihydroBeta-Ionone is present in several plant extracts, and in particular Champaca Absolute. However, only the synthetic version of this molecule is used.
Isomerism :
DihydroBeta-Ionone is a constitutional isomer of Ambrinol, also prepared with Beta-Ionone, but having a very distinctive animalic smell.
Synthesis precursor :
DihydroBeta-Ionone is not a precursor to the synthesis of another compound of olfactory interest.
Synthesis route :
DihydroBeta-Ionone is synthesized from beta-ionone by a catalytic hydrogenation reaction. This reaction uses a palladium, nickel or platinum catalyst. beta-Ionone, like the other ionones, is synthesized from Citral by a cyclization reaction in the presence of acetone.
