1,1,2-Trichloroethane, vinyl trichloride or 1,1,2-TCA, is an organochloride solvent with the molecular formula {{chem2|C2H3Cl3}} and the structural formula {{chem2|CH2Cl\sCHCl2}}. 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-dichloroethylene.{{cite report |title=Toxicological profile for 1,1,2-trichloroethane |publisher=Agency for Toxic Substances and Disease Registry (ATSDR) |date=March 2021 |url=https://www.atsdr.cdc.gov/toxprofiles/tp148.pdf |access-date=2023-08-23 |archive-date=2022-03-05 |archive-url=https://web.archive.org/web/20220305233413/https://www.atsdr.cdc.gov/toxprofiles/tp148.pdf |url-status=live}}

==Toxicity==

1,1,2-Trichloroethane may be harmful by inhalation, ingestion, and skin contact. It is a respiratory and eye irritant. 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.{{cite web | title = Safety (MSDS) data for 1,1,2-trichloroethane |url = https://www.spectrumchemical.com/MSDS/TCI-T0381.pdf}}

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.[https://www.cdc.gov/niosh/npg/npgd0628.html CDC - NIOSH Pocket Guide to Chemical Hazards]
