1,1-dichloroethane (1,1-DCA) is a colorless liquid chlorinated hydrocarbon compound with a sweet odor. It is commonly used as an industrial solvent, as a chemical intermediate in the production of vinyl chloride and perchloroethylene, and as a gasoline additive. 1,1-DCA can be harmful if inhaled, ingested, or absorbed through the skin, and long-term exposure may result in damage to the liver, kidneys, and nervous system, as well as an increased risk of cancer. It is classified as a hazardous substance by the United States Environmental Protection Agency (EPA) and several other organizations. The production and use of 1,1-DCA have been restricted in several countries due to its potential environmental and health impacts.
