Uses
It is commonly used as artificial flavoring such as pineapple flavoring in alcoholic beverages (i.e. martinis, daiquiris etc); solvent; in perfumery products and as a plasticizer for cellulose.
Production
It can be synthesized by reacting ethanol and butyric acid. This is a condensation reaction, meaning water is produced in the reaction as a byproduct.
