Definition
ChEBI: Propyl butyrate is a butyrate ester resulting from the formal condensation of the hydroxy group of propanol with the carboxy group of butyric acid. It has a role as a human metabolite, a plant metabolite and an insect attractant. It is functionally related to a propan-1-ol.
Preparation
From propyl alcohol and butyric acid in the presence of p-toluenesulfonic acid in benzene solution at the boil.
Aroma threshold values
Detection: 0.8 to 124 ppb
Taste threshold values
Taste characteristics at 20 ppm: sweet, fruity, tutti-frutti, bubble gum and pineapple-like, with a slight green nuance.
Synthesis Reference(s)
The Journal of Organic Chemistry, 58, p. 6421, 1993 DOI: 10.1021/jo00075a043
General Description
Natural Occurrence: Apple, banana, kiwi, melon, papaya, passion fruit, rum and strawberry.
