能溶于水，水中溶解度:1900 g/l (22 c)，溶于甲醇、乙醚和热苯，微溶于冷苯。 用作有机合成原料。 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 2-Hydroxyisobutyric acid is used as an electrolyte in the separation of the metal ions by on-line cyclic voltammetry. It is also used as a building block for the synthesis of polymers. Its conjugate base, 2-hydroxybutyrate is utilized to catabolize L-threonine as well as synthesize glutathione. Further, it is used as an indicator for the early detection insulin resistance in non-diabetic subjects.
