An organic ester is a compound that is formed when an organic acid reacts with an alcohol. It is commonly used in the manufacturing of perfumes, flavors, and plastics. There are several synonyms for the term organic ester depending on its composition and use, such as ethyl acetate, propyl formate, butyl butyrate, methyl benzoate, and isoamyl acetate. Ethyl acetate is commonly used in nail polish remover and as a solvent for fats, oils, and resins. Propyl formate is known for its fruity odor and is used in the production of food flavors. Butyl butyrate is used in the manufacture of artificial fruit flavors, while methyl benzoate is useful in perfumery and as a solvent for cellulose esters.
