Chemistry & Uses
Uses in perfumery :
This molecule is used in floral notes as gardenia, in reconstitutions of rhubarb and grapefruit, in woody notes as vetiver and sandalwood. It brings a milky and warm nuance in eaux fraiches for example.
Year of discovery :
Data not available.
Natural availability :
Woodinyl acetate is not found in nature.
Isomerism :
In its molecular structure, Woodinyl acetate has one asymetric carbon, giving birth to two enantiomers. These are not used separately in perfumery. Woodinyl acetate also is a constitutional isomer of Dimethylbenzylcarbinyl Butyrate, whose molecular structure is similar. The latter is nevertheless more reminiscent of dry fruits, while Woodinyl acetate is of rhubarb.
Synthesis precursor :
Woodinyl acetate is not used for the synthesis of another compound used in perfumery.
Synthesis route :
Woodinyl acetate is prepared with an esterification reaction. This reaction involves 4-methyl-4-phenylpentanol and acetic acid. It is catalyzed by the use of a low quantity of one strong acid as sulfuric acid. This reaction yield can be improved thanks to the use of chloroacetic acid or acetic anhydride instead of acetic acid.
Stability :
acetates may form acetic acid through time. Aromatic molecules are said to be chromophorous. This means that they may color under the effect of light.
Other comments :
Woodinyl acetate is less green and metallic than Styrallyl acetate. It is different from Nootkatone for example, according to its warm woody and floral undernotes.
