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.

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
