General description

α-Hydroxyisobutyric acid (2-hydroxyisobutyric acid) is the building block for polymer synthesis. It forms complexes with Eu(III) and has been studied by time resolved fluorescence spectroscopy.

Application

α-Hydroxyisobutyric acid was used as background electrolyte for separation and detection of the metal ions by on-line cyclic voltammetry.

Methyl-tert-butyl ether (MTBE) is widely used as an additive to gasoline to increase oxygen content and reduce tail pipe emission of pollutants. Therefore, widespread human exposure may occur. To contribute to the characterization of potential adverse effects of MTBE, its

Fuel oxygenates such as methyl and ethyl tert-butyl ether (MTBE and ETBE, respectively) are degraded only by a limited number of bacterial strains. The aerobic pathway is generally thought to run via tert-butyl alcohol (TBA) and 2-hydroxyisobutyrate (2-HIBA), whereas further

After exposure to methyl tert-butyl ether (MTBE), a gasoline additive, only one metabolite [tert-butyl alcohol (TBA), <1% of dose] has been identified in human urine [Nihlén, A., et al. (1998) Toxicol. Appl. Pharmacol. 148, 274-280]. In the study presented here
