2-Bromoethanol Usage And Synthesis
Chemical Properties colourless liquid
Uses 2-Bromoethanol is used in selective reduction of nitroarenes (PcFe(II)/NaBH4/2-bromoethanol catalyst system).
Uses Ethylene bromohydrin is not used much forany commercial purpose. The risk of expo sure to this compound arises when ethyleneoxide reacts with hydrobromic acid.
General Description Colorless to dark brown liquid. Sweet burning taste.
Air & Water Reactions Hygroscopic. Water soluble.
Reactivity Profile 2-Bromoethanol forms an azeotrope with water; hydrolysis of aqueous solutions is accelerated by heat, alkalis and acids.
Hazard Irritant to eyes and mucous membranes.
Health Hazard The vapors of ethylene bromohydrin are anirritant to the eyes and mucous membranes.It is corrosive to the skin. Ingestion of thiscompound can produce moderate to severetoxic effects. The target organs are the CNS,gastrointestinal tract, and liver. The lethaldose in mice by the intraperitoneal route was80 mg/kg.
Ethylene bromohydrin manifested car cinogenicity in test animals. It caused tumorsin lungs and the gastrointestinal tract in micefrom intraperitoneal (150 mg/kg/8 weeks)and oral (43 mg/kg/80 weeks) dosages,respectively. It is a mutagen, positive to thehistidine reversion–Ames test.
Fire Hazard 2-Bromoethanol is combustible.
