1,2-Dichloroethylene is used as a solvent for waxes and resins, in rubber extraction, and as a coolant in refrigeration plants. The cis- and trans- isomers have slightly different physical, chemical, and biological properties. The trans-isomer is more widely used. 1,2-Dichloroethylene is frequently detected at federal and state hazardous waste sites across the country.
