Description

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.
