Common NameIsobutanol
DescriptionIsobutanol is an aliphatic alcohol. Isobutanol is a colorless, flammable, organic compound with a characteristic smell. Isobutanol is widely used in industry, as a solvent in chemical reactions, as well as being a useful starting material for organic synthesis. Isobutanol is a flammable liquid that should be stored and used in well-ventilated areas. It is moderately irritating to the skin and greatly irritating to the eyes, mucous membranes and respiratory tract. Exposure to high concentrations of its vapour can cause temporary narcosis. Isobutanol is occasionally found as a volatile component of urine and arises from gut microbial metabolism. Isobutanol is used as one of the markers to measure occupational exposure to a mixture of solvents. Aliphatic alcohols levels increase in both diabetes mellitus and insulin-dependent diabetes patients. (PMID:5556886 , 2477620 , 9143482 , 7627316 , 2288731 ). Isobutanol is a microbial metabolite found in Clostridium, Cupriavidus, Escherichia, Geobacillus, Saccharomyces and Synechococcus (PMID:19946322 ).
