Metabolite Identification
Common NameEthyl pentanoate
DescriptionEthyl pentanoate, commonly known as ethyl valerate, is an organic compound used in flavouring foods and enhancing the aroma of cosmetics. It is an ester with the molecular formula C7H14O2. This colourless liquid is poorly soluble in water but miscible with organic solvents. Ethyl pentanoate is found naturally in a variety of alcoholic beverages such as various wines, Bantu beer, and sake. It is also found in other foods such as honey, apple, banana, morello cherry, guava and a number of other fruits. Industrially, ethyl pentanoate is used as a flavouring agent and has a pleasant apple or pineapple-like aroma or scent and a strawberry or pineapple-like taste. It can also be found in tropical-scented cosmetics.
