Ethyl propionate is an organic compound with formula C2H5O2CCH2CH3. It is the ethyl ester of propionic acid. It is a colorless volatile liquid with a pineapple-like odor.[3] Some fruits such as kiwis[4] and strawberries[5] contain ethyl propionate in small amounts.
Uses and reactions
It is also used in the production of some antimalarial drugs including pyrimethamine.[6]
Ethyl propionate can be synthesized by the Fischer esterification of ethanol and propionic acid:
- CH3CH2OH + CH3CH2CO2H → CH3CH2O2CCH2CH3 + H2O
It participates in condensation reactions by virtue of the weakly acidic methylene group.[7]
