What is DL-4-Amino-3-hydroxybutyric acid?
Definition
ChEBI: Gamma-amino-beta-hydroxybutyric acid is a gamma-amino acid comprising 4-aminobutyric acid having a 2-hydroxy substituent. It is a gamma-amino acid and a 3-hydroxy monocarboxylic acid. It is functionally related to a butyric acid. It is a conjugate acid of a 4-amino-3-hydroxybutanoate. It is a tautomer of a gamma-amino-beta-hydroxybutyric acid zwitterion.
Purification Methods
Purify GABOB through a Dowex 50Wx8 resin, eluting with 1.3N NH4OH, evaporating and crystallising the residue by dissolving it in H2O and adding EtOH. It is an anticonvulsant. [Renaud & Seebach Synthesis 424 1986, Takano et al. Tetrahedron Lett 29 795 1988, Beilstein 4 IV 3187.]
