Meaning and Definition
A colorless, volatile chlorinated hydrocarbon with the formula C₂H₃Cl₃, used as a solvent and in industrial cleaning applications.
It refers specifically to either of two isomers: 1,1,1-trichloroethane (methyl chloroform), a once-common solvent and degreaser, or 1,1,2-trichloroethane. Due to its ozone-depleting properties, its production and use are now heavily restricted under the Montreal Protocol.

Its production and consumption are severely restricted globally under the Montreal Protocol. Some limited essential uses or stockpiles may exist, but it is not in general circulation.
They are different chemical compounds. Trichloroethane (C2H3Cl3) is an alkane. Trichloroethylene (C2HCl3) is an alkene, commonly used as a metal degreaser. Both are chlorinated solvents but have different properties and regulations.
You are most likely to encounter it in specialised contexts: environmental science textbooks, historical industrial documents, chemical safety legislation, or site contamination reports.
No. Due to its health risks (toxicity) and environmental impact (ozone depletion), consumer products containing it have not been legally manufactured for general use in most countries for decades.
