Ethyl formate is an ester formed when ethanol (an alcohol) reacts with formic acid (a carboxylic acid). Ethyl formate has the characteristic smell of rum and is partially responsible for the flavor of raspberries,^[3] occurring naturally in some plant oils, fruits, and juices. Ethyl formate does not occur naturally in the animal kingdom.^[4]
