1,2-Dichloroethane, also known as ethylene dichloride, is a colorless, sweet-smelling organic compound. It is primarily used as an industrial solvent and in the production of vinyl chloride, which is a key ingredient in making polyvinyl chloride (PVC) plastic. This chemical has a boiling point of 83.5 °C and is soluble in water and organic solvents. Due to its potential health risks, including being a possible human carcinogen, its use is regulated in many countries. Proper safety measures are essential when handling 1,2-dichloroethane to minimize exposure.
