DL-Asparagine monohydrate Chemical Properties,Uses,Production
Chemical Properties
white fine crystalline powder, odorless; soluble in acid or alkali solution, slightly soluble in water, insoluble in ethanol, ether and other organic solvents.
Uses
DL-asparagine is a racemic mixture of the non-essential amino acids, L and D-aparagine. It is generally used in growth-media for bacteria-growth. DL-Asparagine monohydrate can also be used to synthesize other salts such as DL-asparaginium perchlorate, DL-asparaginium nitrate and dimethyl DL-aspartate.
Preparation
DL-Asparagine monohydrate was synthesized by dissolving maleic anhydride in 1,4-dioxane solution and refluxing with benzylamine after ammonolysis, followed by catalytic hydrogenation.
Definition
ChEBI: An alpha-amino acid in which one of the hydrogens attached to the alpha-carbon of glycine is substituted by a 2-amino-2-oxoethyl group.
reaction suitability
reaction type: solution phase peptide synthesis
