2-(L-Alanylamino)-L-butyric acid

C. H. Görbitz

Abstract: The title dipeptide, C₇H₁₄N₂O₃, with the common name L-alanyl-L-2-aminobutyric acid, has previously been crystallized as the 0.33-hydrate [Görbitz (2002). Acta Cryst. C58, o533-o536]. By using 1,1,1,3,3,3-hexafluoropropan-2-ol as the solvent, water-free crystals were obtained. The two crystal structures are related (P2₁, Z' = 3 for both), but the molecular conformations and details of the hydrogen-bonding network are different.
