1,2-Dichloroethene, commonly called 1,2-dichloroethylene or 1,2-DCE, is an organochloride with the molecular formula C2H2Cl2. It is a highly flammable, colorless liquid with a sharp, harsh odor. It can exist as either of two geometric isomers, cis-1,2-dichloroethene or trans-1,2-dichloroethene, but is often used as a mixture of the two. It is insoluble in water, but soluble in ethanol, diethyl ether, acetone, benzene, and chloroform.
The major health effect of inhalation of vapors of 1,2-DCE is narcosis; it has been used in a combination with diethyl ether as an anesthetic. In high concentrations, exposure to 1,2-DCE causes central nervous system depression; in milder exposures, it can produce nausea, vomiting, weakness, tremor, epigastric cramps, burning of the eyes and vertigo.
