설명

애플리케이션

β-Hydroxyisovaleric acid can be used as as a precursor for steroid alcohols.

It is widely used in the synthesis of the anthrax tetrasaccharide and its analogs as anthrax vaccine candidates. β-hydroxyisovaleric acid can also be used in the synthesis of β-lactones by intramolecular dehydration condensation using 2-methyl-6-nitrobenzoic anhydride (MNBA).
