Description and Uses
2-bromoethanol, a halogenated alipathic hydrocarbon, is a widely used industrial chemical. It is also a contaminant in food such as wheat and flour during treatment with ethylene oxide. 2-Bromoethanol was also found as a metabolite of 1,2-dibromoethane. A known carcinogen in experimental animals. 2-Bromoethanol is highly toxic in vivo and is a potent mutagen. Fatty acid conjugates of 2-bromoethanol that have been identified after 2-bromoethanol administration to rats may explain the long term 2-bromoethanol accumulation and retention in body tissues. Chronic exposure to 2-bromoethanol causes liver and kidney toxicity. 2- Bromoethanol also induces extensive lipid peroxidation in rat liver, kidney and testis slices and inhibits liver mitochondria respiration[1].
2-Bromoethanol is used in selective reduction of nitroarenes (PcFe(II)/NaBH4/2-bromoethanol catalyst system). It is not used much forany commercial purpose. The risk of exposure to this compound arises when ethylene oxide reacts with hydrobromic acid. It is used as a solvent and organic synthetic raw material. 2-Bromoethanol finds application in the synthesis of 2-piperidin-1-yl-ethanol by reacting with piperidine.
