Description and Uses

In commercial practice amyl invariably means isoamyl, unless it is prefaced by the n- for normal. Isoamyl acetate has a powerful, fruity odor with a bittersweet taste reminiscent of pear. If impure, the odor is strong, penetrating, and almost shocking. Usually prepared by esterification of commercial isoamyl alcohol with acetic acid.
