Butyl hexanoate has a characteristic pineapple-like odor.

Reported found in fresh apple, apple juice, apricot, banana and orange juice.

Butyl Hexanoate is used in preparation of low viscosity and high flammability ester synthetic oil.

ChEBI: Butyl hexanoate is a hexanoate ester obtained by the formal condensation of the carboxy group of hexanoic acid (caproic acid) with butan-1-ol. It is a volatile compound found in apples and peaches. It has a role as a flavouring agent, a human metabolite, a plant metabolite and an insect attractant. It is a hexanoate ester and a volatile organic compound. It is functionally related to a butan-1-ol.

By esterification of hexanoic acid with n-butyl alcohol in benzene solution in the presence of p-toluene sulfonic acid; it is also formed in the fermentation of carbohydrates yielding n-butyl alcohol and acetone.

Detection: 700 ppb to 10 ppm

Taste characteristics at 10 ppm: fruity, pineapple, green, waxy, tutti-frutti with a slight fermented fruit note.
