L-Arginine hydrochloride Usage And Synthesis |
Chemical Properties | White crystalline powder |
Uses | gastric acid depressant |
Uses | An essential amino acid for human development. Precursor for nitric oxide. Ammonia detoxicant (hepatic failure); diagnostic aid (pituitary function). |
Brand name | R-Gene 10 (Pharmacia & Upjohn). |
Safety Profile | Moderately toxic by intraperitoneal route. Mildly toxic by ingestion. An experimental teratogen. When heated to decomposition it emits very toxic fumes of NOx and HCl. |
Purification Methods | A likely impurity is ornithine. Crystallise the salt from H2O at pH 5-7, by adding EtOH to 80% (v/v). [Greenstein & Winitz The Chemistry of the Amino Acids J. Wiley, Vol 3 p 1841 1961, Beilstein 4 IV 2649.] |
