(also halothane), CF3—CHBrCl(1, 1, 1-trifluoro-2-chloro-2-bromoethane), a colorless liquid, with a chloroform odor, a boiling point of 50°C, and a density of 1.87 g/cm3 (at 20°C). Fluothane is practically insoluble in water but is soluble in alcohol and most other organic solvents. Since it decomposes gradually on exposure to light, it is stabilized, for example, with 0.01–0.1 percent alcohol or thymol. Fluothane is usually prepared from chlorotrifluoroethylene:
It is used in medicine as an effective inhalation anesthetic.
