Other names :
1,3-dimethyl-3-phenyl butyl acetate ; Isobutyl phenylethyl carbinyl acetate ; Corps 53 ; Rhubarb body ; 4-methyl-4-phenyl-2-pentyl acetate ; 4-methyl-4-phenylpentan-2-yl acetate ; Vetikol acetate ; Vetikyle acetate ; Veticol acetate ; Veticyle acetate ; Corps rhubarb ; Vetac
Volatility :
Head/Heart
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.
Natural availability :
Woodinyl acetate is not found in nature.
Year of discovery :
Data not available.
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.
Price Range :
€€€
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.

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.
Synthesis precursor :
Woodinyl acetate is not used for the synthesis of another compound used in perfumery.
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.
