Appearance

Colorless liquid, but may turn pale yellowish under storage.

Solubility

Insoluble in water, miscible with alcohol, perfume and flavor materials.

Odor

Sweet-green, somewhat floral odor with a distinctly fruity note, sweet-caramellic undertone.

Uses in perfumery

Rarely used in perfumery, probably as a trace component in Violet type fragrances or as a modifier-topnote material for fruity-green topnotes in modern fragrances.

Uses in flavor

Used in flavor compositions for imitation Chocolate, Coffee, Tutti-frutti, Whisky/Brandy, etc.

Production

Produced from Furfurhydracrylic acid with iso-Amyl alcohol by direct esterification. The acid is obtained by hydrogenation of 2-Furanacrylic acid, which in turn is prepared from Furfural plus Malonic acid with Pyridine as a catalyst. Furfural is a common commercial chemical obtained by destructive oxidation of waste carbohydrates.
