Description
(3R)-3-hydroxy-L-aspartic acid is a 3-hydroxy-L-aspartic acid. It is a conjugate acid of a (3R)-3-hydroxy-L-aspartate(1-) and a (3R)-3-hydroxy-L-aspartate(2-). It is an enantiomer of a (3S)-3-hydroxy-D-aspartic acid.
Likely impurities are 3-chloromalic acid, ammonium chloride, threo-3-hydroxyaspartic acid. Crystallise it from water. [Greenstein & Winitz The Chemistry of the Amino Acids J. Wiley, Vol 1 p 214, Vol 3 p 2416 1961.]
