Description and Uses
Ethyl butyrate, also known as ethyl butanoate, or butyric ether, is an ester with the chemical formula CH3CH2CH2COO.CH2CH3.It is soluble in propylene glycol, paraffin oil, and kerosene.It has a fruity odor, similar to pineapple.
Ethyl butyrate is used in flavors and fragrances. It is used as a solvent in perfumery products, and as a plasticizer for cellulose. It is used in the preparation of novel 2-cyanopyrimidines as cathespin K inhibitors. It is also used in the synthesis of pyridobenzimidazole derivatives exhibiting antifungal activity by the inhibition of β-1,6-glucan.
