Prenyl acetate

Other comments :

Prenyl acetate is very close to Isoamyl acetate. Their smell is anyway different, as Prenyl acetate is less evoking banana fruit and its sweet aspect. It has a etheric smell instead.

Stability :

Esters tend to form their corresponding acid in stability.

Uses in perfumery :

Prenyl acetate is used for banana and red fruit accords, associated with floral notes to add a fruity aspect and to boost the top note.

Year of discovery :

Data not available.

Isomerism :

Prenyl acetate is a constitutional isomer of cis-3-Hexenyl Formate. The smell of Prenyl acetate also evokes pear fruit and has a green nuance, much less important than in cis-3-Hexenyl Formate.

Synthesis precursor :

Prenyl acetate is not a precursor to the synthesis of another compound of olfactive interest.

Natural availability :

Prenyl acetate is slightly found (less than 1%) in Ylang-Ylang distillation fractions (Ylang-Ylang Extra EO for example). It can be extracted from it on a natural state.

Synthesis route :

Prenyl acetate is synthesized by an esterification reaction between acetic acid and prenol (or 3-methyl-2-butenol). This synthesis can be optimized to get a better yield, replacing acetic acid by acetic anhydride or chloroacetic acid.
