Description and Uses
Isoamyl propionate has an apricot-pineapple odor. The taste is somewhat harsh when freshly distilled but subsequently yields apleasant apricot-plum bittersweet flavor. May be prepared by esterification of propionic acid with the isomeric amyl alcohols obtained from fusel oil and other sources.
Perfumes, lacquers, flavors.
