Tetrachlorodinitroethane is a chlorinated nitroalkane produced by nitration of tetrachloroethylene with dinitrogen tetroxide or fuming nitric acid.^[1]^[2]^[3] It's a powerful lachrymatory agent and pulmonary agent that is six times more toxic than chloropicrin.^[3] Tetrachlorodinitroethane may be used as a fumigant.^[4]
