Safety Profile
Mutation data reported. Whenheated to decomposition it emits toxic fumes of NOx.Purification Methods
S-Arginine crystallises from H2O as the dihydrate and as plates from EtOH. It also crystallises from 66% EtOH. Its solubility in H2O is 15% at 21o. Its isoelectric point is at pH 10.76.
