Summary: 1,1,2-trichloroethane is an isomer of 1,1,1-trichloroethane. It is used as an intermediate in organic synthesis for vinylidine chloride. It has many uses as a solvent. It may form as an impurity of other chemicals, and it may exist as an environmental contaminant from anaerobic degradation of other chemicals. It exists as a colorless liquid at room temperature and has a density of 1.4416 g/mL at 20 C. It is soluble in water up to 4,590 mg/L at 25 C. The compound is classified by the EPA as a Hazardous Air Pollutant (HAPs). As a vapor in the atmosphere it undergoes photochemical reactions with hydroxyl radicals and degrades with a half-life of 50 days. Koc values ranging from 83 – 209 indicate moderate to high mobility. Volatilization from water and soil is expected to be a major fate process.
