DL-Aspartic acid is a racemic mixture of the proteinogenic amino acid L-aspartate and the non-proteinogenic amino acid D-aspartate.
From 490 to 536 g. of ethyl chloroacetate (b.p. 144–145°) is recovered by the distillation.
Although this product cannot be purified by distillation, it contains almost the theoretical amount of nitrogen as shown by Kjeldahl analysis.
During the first few hours the distillate contains ethyl acetate; the distillate obtained during the first hour, amounting to 137 ml., distils below 99° and on saturation with sodium chloride yields 115 ml. of crude ethyl acetate.
A 2675 (OTTO) DL-Aspartic acid, 99% Cas 617-45-8 - used in studies on factors and conditions that enhance semen and sperm quality. Its conjugate base D-aspartate has potential use as a therapeutic agent in the treatment of schizophrenia-related symptoms.
