Isomerism :

Isoamyl Alcohol has no known isomer in perfumery.

Synthesis precursor :

Isoamyl Alcohol can be used in an esterification reaction with acetic acid to form Isoamyl acetate. Reaction with Butyric Acid and Salicylic Acid gives Isoamyl Butyrate and Isoamyl Salicylate respectively. It is also involved in the synthesis of Allyl Amyl Glycolate by reaction with Chloroacetic Acid.

Synthesis route :

The industrial scale preparation of Isoamyl Alcohol is made from fusel oil. Fusel oil is a mixture of liquids from the fermentation of carbohydrates. Fractional distillation of this fermented oil is used to recover Isoamyl Alcohol.

Stability :

Stable in perfumes and diverse functional bases
