Infobox references

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.

Toxicology

Trichloroethane may be harmful by inhalation, ingestion and skin contact. It is a respiratory and eye irritant. Although no definitive studies currently exist, trichlorethane should be treated as a potential carcinogen since laboratory evidence suggests that low molecular weight chlorinated hydrocarbons may be carcinogenic.
