Isoamyl o-hydroxybenzoate Chemical Properties,Usage,Production

Description

Isoamyl salicylate has a characteristic aromatic, strong herbaceous, persistent odor and a bittersweet taste reminiscent of strawberry. May be prepared by esterification of salicylic acid with the isomeric amyl alcohols obtained from fusel oil and other sources.

Chemical Properties

Water-white liquid; sometimes having a faint yellow tinge which should not be pink or red; orchid-like odor. Soluble in alcohol, ether; insoluble in water and glycerol. Combustible.

Chemical Properties

Isoamyl Salicylate has been found in a number of fruit aromas. It is a colorless liquid with a sweet, clover-like odor and is used in perfumery for floral and herbal notes, particularly in soap perfumes.

Chemical Properties

Isoamyl salicylate has a pleasant, sweet, slightly floral, herbaceous-green odor and a bittersweet taste reminiscent of strawberry. Isoamyl o-hydroxybenzoate is a colorless oily liquid. Sp.Gr. 1.06. B.P. 277℃. Insoluble in water, soluble in alcohol, perfume and flavor materials.

Occurrence

Reported found in Burley tobacco, grapes, black tea and rum

Uses

Isoamyl Salicylate is used in preparation of Hydrogen Peroxide responsive Oxalic Acid derivatives for imaging and therapy.

Uses

Isoamyl o-hydroxybenzoate is used in perfumery and soaps. Extensively used in floral and non-floral perfume types: Very often in Carnation, Hyacinth, Orchid, Tretle, and almost inevitably in Fougere types. Its low cost and worldwide availability makes it one of the most important perfume chemicals. Occasionally used in "Root Beer" type flavors and certain Fruit flavors. Concentra- tion is usually mere traces (a few ppm in finished consumer product).

Preparation

By esterification of salicylic acid with the isomeric amyl alcohols obtained from fusel oil and other sources.

Definition

ChEBI: Isoamyl salicylate is a benzoate ester and a member of phenols. It is functionally related to a salicylic acid.

Aroma threshold values

Aroma characteristics at 1.0%: sweet, floral, soapy, spicy with anise and wintergreen nuances.
