Documented Uses

• For the induction and maintenance of general anesthesia
• Animal Drugs -> FDA Approved Animal Drug Products (Green Book) -> Active Ingredients
• Bromination of 2-chloro-1,1,2-trifluoroethylene to form 1,2-dibromo-1-chloro-1,2,2-trifluoroethane, isomerization of the product with anhydrous aluminum chloride to 1,1-dibromo-1-chloro-2,2,2-trifluoroethane, and reduction of the latter with hydrogen (catalyzed by platinum); the antimony chloride-catalysed reaction of hydrogen fluoride with 1,2-dibromo-1,1,2-trichloroethane.
• Preparation from a mixture of F3CCH2Cl and FCCBrCl: Suckling, Raventos, US 2921098 (1960 to I.C.I.); by rearrangement of F2BrCCHFCl: Scherer, Kuhn, US 2959624 (1960 to Hoechst); from BrClCHCBrCl2: Chapman, McGinty, GB 805764 (1958 to I.C.I.); from Br2ClCCF3: McGinty, US 3082263 (1963 to I.C.I.)
• ... /The use of chlorofluorocarbons for aerosol sprays/ was prohibited in 1979 except for a few specialized items, because of their depleting effect on stratospheric ozone. /Chlorofluorocarbons/
• Halothane is a potent volatile halogenated anesthetic gas that has been linked to many cases of idiosyncratic acute liver injury that are frequently severe. The potential of halothane to cause hepatotoxicity and the greater safety of newer anesthetics has led to a decrease in its use, currently limited to special situations, particularly in children. Because halothane is relatively inexpensive it continues to be used in developing countries.
