2.91 | [Uses]
Anisyl Butyrate is a synthetic flavoring agent that is a stable, color-
less liquid of sweet cassic odor. it should be stored in glass or tin
containers. it will intensify vanilla flavor and is used as a fixative.
it is used in ice cream, candy, and baked goods at 5–15 ppm. | [CAS DataBase Reference]

| Hazard Information | Back Directory | [Chemical Properties]
Anisyl butyrate has a weak, floral, intensely sweet, plum-like odor | [Occurrence]
Has apparently not been reported to occur in nature. | [Application]
Occasionally anisyl butyrate is used in perfumery as a fixative-modifier in fruity-floral fragrance types (Gardenia, Freesia, Magnolia, etc.). Finds some use in flavor compositions for imitation Vanilla, in some fruit flai ors and in Licorice flavorings. Concentrations are usually about 10 to 14 ppm in the finished consumer product. The n-butyrate seems to be slightly less stable than the iso-butyrate, and therefore often show an unpleasant “butyric” topnote due to traces of free acid.
| [Definition]
ChEBI:4-Methoxybenzyl butanoate is a carboxylic ester. It is functionally related to a benzyl alcohol. | [Preparation]
From anisyl alcohol and n-butyric acid. | [Metabolism]
Esters of benzyl alcohol, such as the acetate, are rapidly hydrolysed in vivo to benzyl alcohol, which is then oxidized. The expected general reaction of primary aromatic alcohols in the animal body is oxidation to the corresponding aromatic acid, which is usually excreted as a glycine conjugate and to a lesser extent as an ester glucuronide. In rabbits, benzyl alcohol is almost entirely converted to benzoic acid, which is excreted mainly as hippuric acid . In substituted anisoles with a carboxyl group or a potential carboxyl group attached to the aromatic ring, the ether link is relatively stable |
