L-Lysine hydrochloride Usage And Synthesis
 
Description A white or nearly white, practically odorless, free-flowing, crys talline powder. It is freely soluble in water, but is almost insoluble in alcohol and in ether. It melts at about 260°C with decomposition.
Chemical Properties White crystalline powder
Uses amino acid, nutrient
Uses L-(+)-Lysine Monohydrochloride
Definition ChEBI: The hydrochloride salt of L-lysine
Safety Profile iWdly toxic by ingestion. When heated to decomposition it emits very toxic fumes of HCl and NOx.
Purification Methods Likely impurities are arginine, D-lysine, 2,6-diaminoheptanedioic acid and glutamic acid. Crystallise the monohydrochloride from water at pH 4-6 by adding 4 volumes of EtOH. At above 60% relative humidity it forms a dihydrate. [Birhbaum et al. J Biol Chem 194 455, 468 1952, Kearley & Ingersoll J Am Chem Soc 73 5783 1951, Beilstein 4 IV 2717.]
