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.

Synthesis precursor :

Ambrinol is not a precursor for the synthesis of another material used in 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.

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.

Allergens :

This ingredient does not contain any allergen.

Uses in perfumery :

Ambrinol is used to reproduce the natural Ambergris smell, bringing an animalic, sensual and ambery note, with a fixative effect.

Other names :

ambrinol S, amber naphtalenol, ambrinol-alpha, alpha-ambrinol, ambrinol 95, 2-hydroxy-2,5,5-trimethyl-1,2,3,4,4a,5,6,7-octahydronaphtalene, 1,2,3,4,4a,5,6,7-octahydro-2,5,5-trimethyl-2-naphtalenol, 2,5,5-trimethyl-octahydro-2-naphtalenol

Other comments :

Ambrinol can be compared with Ambrein or DihydroBeta-Ionone, as it is used to reproduce the smell of natural Ambergris.
