DL-3-Aminobutyric acid Usage And Synthesis

Synthesis Reference(s)

The Journal of Organic Chemistry, 23, p. 94, 1958 DOI: 10.1021/jo01095a604

Purification Methods

Crystallise the acid from aqueous EtOH or MeOH/Et2O. Also crystallise it by heating a slightly diluted EtOH solution and adding Me2CO. It gives a purple spot with RF 0.89 on paper chromatography using 80% aqueous phenol (the -amino acid has RF 0.74).
