| | Aminoacetonitrile hydrochloride Usage And Synthesis |
| Chemical Properties | White to light brown solid | | Uses | Used as pharmaceutical intermediates, organic synthetic raw material transportation. | | Application | Aminoacetonitrile is a useful synthetic intermediate. It is a reagent used to synthesize dipeptide nitriles as reversible and potent cathepsin S inhibitors. It can also used to prepare substituted cyclic ureas as possible HIV protease inhibitors. | | Preparation | Synthesis of Aminoacetonitrile Hydrochloride by Reaction of Aminoacetonitrile with Hydrogen Chloride in Methanol: mixing the aminoacetonitrile with hydrogen chloride methanol solution, reacting at 45-50°C for 1-2 hours, cooling to below 5°C, filtering, and centrifugalizing to obtain the aminoacetonitrile hydrochloride, wherein in the hydrogen chloride methanol solution, the content of hydrogen chloride is 30-50 wt%, and the water content is less than or equal to 1%.
Preparation method of aminoacetonitrile hydrochloride | | Safety Profile | An experimental
teratogen. Experimental reproductive
effects. When heated to decomposition it
emits toxic fumes of NOx and HCl. | | Purification Methods | The salt recrystallises from dilute EtOH as hygroscopic leaflets. It is best to crystallise it from absolute EtOH/Et2O (1:1) and then recrystallise it from absolute EtOH. The melting point recorded ranges from 144o to 174o. The free base has b 58o/15mm with partial decomposition.
