arbon tetrachloride, also known by many other names (the most notable being tetrachloromethane, also recognized by the IUPAC), carbon tet in the cleaning industry, Halon-104 in firefighting and Refrigerant-10 in HVACR, is an organic compound with the chemical formula CCl4. The hydrocarbons or any carbon compounds containing more than one halogen atom are known as polyhalogen compounds. Many of these compounds are useful in industry and agriculture.

Carbon Tetrachloride is a clear, colorless, volatile and very stable chlorinated hydrocarbon. Carbon Tetrachloride is used as a solvent for oils and fats, as a refrigerant and as a dry-cleaning agent. Inhalation of its vapors can depress central nervous system activity and cause degeneration of the liver and kidneys. Carbon Tetrachloride is reasonably anticipated to be a human carcinogen based on evidence of carcinogenicity in experimental animals. (NCI05)
