Fluoroethyl fluoroacetate, or more accurately 2-fluoroethyl fluoroacetate, is an organic compound with the chemical formula FCH2CO2CH2CH2F. It is the fluoroacetate ester of 2-fluoroethanol, or in other words, the 2-fluoroethyl ester of fluoroacetic acid. 2-Fluoroethyl fluoroacetate is two times more toxic than methyl fluoroacetate.[3]
