Amyl salicylate

Uses in perfumery :

Amyl Salicylate is used in white flowers, carnation, fougere, ambery and vanillic notes.

Year of discovery :

Initially marketed under the name Trefol, Amyl Salicylate was first used in the perfume Trèfle Incarnat - L.T. Pivert (1898) First synthesized in 1854 by reaction of salycile chloride with amyl alcohol by Drion et al.

Natural availability :

Amyl Salicylate is present in trace amounts in Osmanthus Absolute. It can therefore be extracted, but it is mostly the synthetic compound that is used in perfumery.

Isomerism :

PhenoxyEthyl IsoButyrate is a constitutional isomer of Amyl Salicylate. It smell is closer to rose than jasmine, and is not solar.

Synthesis precursor :

Amyl Salicylate is not a precursor to the synthesis of another compound of olfactory interest.

Synthesis route :

Like other Salicylates, Amyl Salicylate is synthesized by an esterification reaction between salicylic acid and amyl alcohol (or pentenol). This reaction is catalysed by the presence of a strong concentrated acid such as sulfuric acid in the reaction medium.

Stability :

May form Salicylic acid through time.
Most of the time, the occurrence of a benzenic cycle in a molecule causes a coloration of this molecule through time.
Unstable in acidic products, except antiperspirants, and in bleach.

Other comments :

Isoamyl Salicylate has a more metallic and fruity aspect, while Amyl Salicylate has a pronounced jasmine note.
It is one of the most powerful salicylates.
