Tribromoethanol is a chemical compound from the group of alcohols . It is used in veterinary medicine as a sedative for intraperitoneal injection anesthesia of rodents .
synthesis
2,2,2-tribromoethanol is by reaction of aluminum ethoxide and elemental prepared bromine.
Applications
Tribromoethanol is used as a concentrate in a mass concentration of 55% in tertiary amyl alcohol under the name Avertin for injection anesthesia; this is applied as a 1.2–2.5% solution in physiological saline solution . Alternatively, tribromoethanol with buprenorphine or ketamine with xylazine are used. While the toxicity is low and the therapeutic index is large, the narcotic effect has been described as variable.
