Tetrachloroethylene, also known under the systematic name tetrachloroethene, or perchloroethylene (“perc” or “PERC“), and many other names, is a chlorocarbon with the formula Cl2C=CCl2. It is a colorless liquid widely used for dry cleaning of fabrics, hence it is sometimes called “dry-cleaning fluid”. It has a sweet odor detectable by most people at a concentration of 1 part per million (1 ppm).
