Carbon Tetrachloride

CAS ID #: 56-23-5

Affected Organ Systems: Cardiovascular (Heart and Blood Vessels), Hepatic (Liver), Neurological (Nervous System)

Cancer Classification: NTP: Reasonably Anticipated to be a Human Carcinogen

Chemical Classification: Volatile organic compounds

Summary: Carbon tetrachloride is a manufactured chemical that does not occur naturally. It is a clear liquid with a sweet smell that can be detected at low levels. It is also called carbon chloride, methane tetrachloride, perchloromethane, tetrachloroethane, or benziform. Carbon tetrachloride is most often found in the air as a colorless gas. It is not flammable and does not dissolve in water very easily. It was used in the production of refrigeration fluid and propellants for aerosol cans, as a pesticide, as a cleaning fluid and degreasing agent, in fire extinguishers, and in spot removers. Because of its harmful effects, these uses are now banned and it is only used in some industrial applications.
