Trichloroethylene is a halogenated hydrocarbon, which comes in form of a colorless liquid at standard conditions. It has a specific smell, similar to chloroform. Trichloroethylene is an excellent solvent, and most of its industrial uses are related to the mentioned property. It has also been used as a dry cleaning solvent, although it has been mostly replaced with tetrachloroethylene which is less harmful. For some time, it has also been used as an anesthetic. However, it has also mostly been replaced by other compounds (halothane). Trichloroethylene is also used as a degreaser.

Although it is gradually being replaced with other solvents, trichloroethylene can still be bought in certain stores which sell paint, varnishes, solvents and similar products. Such trichloroethylene is usually of technical grade. In case one needs higher purity, this compound can also be ordered from chemical selling companies.
