Ethyl chloroformate is the ethyl ester of chloroformic acid. It is a reagent used in organic synthesis for the introduction of the ethyl carbamate protecting group[2] and for the formation of carboxylic anhydrides. It is capable of producing GABAergic anxiolytic/sedative/anesthetic effects (in order of increasing dose-effect threshold) in sufficient doses but produces potent hemotoxic and neurotoxic effects doses below the anesthetic threshold (roughly equivalent to the anxiolytic threshold) and was therefore never used for medical applications.
