Application

2-Hydroxy-2-methylbutyric acid can be used as:
  • A complexing agent in a new electrolytic system, applicable in the isotachophoretic lanthanide separation.
  • An aldehyde surrogate to prepare pyrrolo[1,2-a]quinoxaline derivatives by reacting with 2-(1H-pyrrol-1-yl)aniline.
  • A starting material to synthesize Cr(V) reagent named sodium bis(2-hydroxy-2-methylbutyrato)oxochromate(V) (Aldrich cat. no. ALD00006) applicable in the total synthesis of (−)-taxuyunnanine D.
