Infobox disclaimer and references

1,1,2,2-Tetrachloroethane is a chlorinated derivative of ethane. It has the highest solvent power of any chlorinated hydrocarbon.[1] As a refrigerant, it is used under the name R-130.

Additional recommended knowledge

It was once widely used as a solvent and as an intermediate in the industrial production of trichloroethylene, tetrachloroethylene, and 1,2-dichloroethylene.[2] However, 1,1,2,2-tetrachloroethane is no longer used much in the United States due to concerns about its toxicity.[3]

Chronic inhalation exposure in humans results in jaundice and an enlarged liver, headaches, tremors, dizziness, numbness, and drowsiness and the U.S. Environmental Protection Agency as a Group C possible human carcinogen.[3]
