Utilisation

Chemistry & Uses

Year of discovery :

Data not available.

Natural availability :

Gamma-Hexalactone is present in several fruits. However, it is synthetic Gamma-Hexalactone which is more often used in perfumery.

Isomerism :

The asymmetric carbon of Gamma-Hexalactone is responsible for the presence of two enantiomers of this molecule. The (R) enantiomer of the molecule is greener than the other isomer, more woody.

Synthesis precursor :

Gamma-Hexalactone is not a precursor to the synthesis of another compound of olfactory interest.

Synthesis route :

Like some other lactones, Gamma-Hexalactone can be synthesized by an intramolecular esterification reaction, using 4-hydroxyhexanoic acid and concentrated sulfuric acid, for example, in a catalytic amount.

Stability :

Lactones tend to polymerize through time, making them more viscous and leading to a phase shift in alcohol.

Other comments :

The smell of Gamma-Hexalactone is close to the one of Methyl Laitone® because of its fruity Coumarin note, reminiscent of coconut.
