1,1,2-Trichloroethane, or 1,1,2-TCA, is an organochloride solvent with the molecular formula C2H3Cl3 and the structural formula CH2Cl—CHCl2. It is a colourless, sweet-smelling liquid that does not dissolve in water, but is soluble in most organic solvents. It is an isomer of 1,1,1-trichloroethane, and a byproduct of its manufacture.

It is used as a solvent and as an intermediate in the synthesis of 1,1-dichloroethene. [4]

1,1,2-TCA is a central nervous system depressant and inhalation of vapors may cause dizziness, drowsiness, headache, nausea, shortness of breath, and unconsciousness. [5]

Toxicology

Trichloroethane may be harmful by inhalation, ingestion, and skin contact. It is a respiratory and eye irritant.

The Occupational Safety and Health Administration and National Institute for Occupational Safety and Health have set occupational exposure limits to 1,1,2-Trichloroethane at 10 ppm over an eight-hour time-weighted average. [6]
