Uses in perfumery :

Isoamyl Phenyl acetate is used in chocolate, floral and fruity notes such as pineapple, peach and pear.

Year of discovery :

Data not available.

Natural availability :

Natural Isoamyl Phenyl acetate is present in Peppermint EO and Artemisia afra, present in Kenya in a very small amount. Therefore, this molecule can only be extracted in a very small amount, and for this particular reason, synthetic Isoamyl Phenyl acetate in most often used in perfumery.

Isomerism :

Amyl Phenyl acetate is a position isomer of Isoamyl Phenyl acetate. They have a quite different note : le last one has a chocolate-like note, while the first one is greener and less honeyed. Moreover, Floropal® is a constitutional isomer of IsoAmyl Phenyl acetate. It has a sulfuric smell reminiscent of Rhubarb, while IsoAmyl Phenyl acetate is sweeter and rosier.

Synthesis precursor :

Isoamyl Phenyl acetate is not a precursor to the synthesis of another compound of olfactory interest.

Synthesis route :

Like most esters, Isoamyl Phenyl acetate is synthesized by an esterification reaction between Phenylacetic Acid (obtained from benzyl chloride and sodium cyanide) and Isoamyl Alcohol. This reaction is catalysed by a strong acid such as concentrated sulfuric acid, present in the reaction medium in a small amount.

Stability :

May form Phenylacetic acid through time under the effect of heat.
Most of the time, the occurrence of a benzenic cycle in a molecule causes a coloration of this molecule through time
