Carbon tetrachloride (CCl4) has been widely used as a dry-cleaning agent, in fire extinguishers and in the manufacture of other halogenated hydrocarbons. At toxic doses, CCl4 exposure can damage the liver and kidneys. This toxicity results from CYP2E1-dependant reduction of CCl4 to the reactive trichloromethyl radical (CCl3.).
