Chemistry & Uses
Uses in perfumery :
Ambrinol is used to reproduce the natural Ambergris smell, bringing an animalic, sensual and ambery note, with a fixative effect.
Year of discovery :
Data not available.
Natural availability :
Ambrinol is one of the components of Ambergris, previously used for its sensual and animalic notes, and extracted as a tincture in alcohol. Then, only synthetic Ambrinol is used for perfumery.
Isomerism :
Ambrinol frequently used in perfumes is Alpha-Ambrinol. Beta-Ambrinol also exists, but is much less used. On the other hand, Ambrinol has one asymmetric carbon, giving birth to two possible enantiomers for this molecule. It is anyway a mixture of these isomers that is used in perfumery. Eventually, Ambrinol also is a constitutional isomer of DihydroBeta-ionone, also prepared from Beta-Ionone.
Synthesis precursor :
Ambrinol is not a precursor for the synthesis of another material used in perfumery.
Synthesis route :
Ambrinol can be synthesized thanks to Beta-Ionone. This molecule can undergo thermolysis (chemical decomposition under the effect of heat), bringing dehydroambrinol. Hydrogenation in methanol, in the presence of Raney nickel catalysor leads to Ambrinol.
Stability :
Stable in perfumes and various functionnal bases.
Other comments :
Ambrinol can be compared with Ambrein or DihydroBeta-Ionone, as it is used to reproduce the smell of natural Ambergris.
