1,1,2-Trichloroethane, or 1,1,2-TCA, is an organochloride solvent with the molecular formula C2H3Cl3. 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.
It is used as a solvent and as an intermediate in the synthesis of 1,1-dichloroethane.
1,1,2-TCA is a central nervous system depressant and inhalation of vapors may cause dizziness, drowsiness, headache, nausea, shortness of breath, unconsciousness, or cancer.[citation needed]
Toxicology
Trichloroethane may be harmful by inhalation, ingestion and skin contact. It is a respiratory and eye irritant. Although no definitive studies currently exist, trichloroethane should be treated as a potential carcinogen since laboratory evidence suggests that low molecular weight chlorinated hydrocarbons may be carcinogenic.[2]
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.[3] It is considered to be a potential occupational carcinogen.
