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 also the chemical responsible for the flavor of raspberries. It occurs naturally in the body of ants and in the stingers of bees. Ethyl formate is studied extensively for use in the preparation of pesticide fumigants for grain. Also used widely in fragrance formulations.
