General description

α-Hydroxyisobutyric acid is a versatile building block in organic synthesis. It serves as a precursor in the synthesis of compounds like isobutylene glycol and methacrylic acid

Application

α-Hydroxyisobutyric acid (HIBA) can be used as:
  • A chelating agent to improve the separation of lanthanides and actinides by liquid chromatography.
  • In the synthesis of room temperature–stabilized, pure, nanocrystalline β-NiMoO4.
