| | Acetamidine hydrochloride Usage And Synthesis |
| Uses | Acetamidine Hydrochloride is a compound useful in organic synthesis. | | Chemical Properties | WHITE FINE CRYSTALLINE POWDER | | Uses | Acetamidine hydrochloride was used in the preparation of decarboxyectoine. It was also used in the synthesis of ethyl 4-(4-hydroxyphenyl)methylidene-2-methyl-5-oxo-1-imidazolacetate. | | General Description | Acetamidine hydrochloride is an amidine salt and its conversion to 2,4,6-trimethyl-sym-triazine has been studied. | | Purification Methods | The hydrochlorde can be recrystallised from small volumes of EtOH. Alternatively it is dissolved in EtOH, filtered, Et2O is added; filter the crystalline salt off under N2 and dry it in a vacuum desiccator over H2SO4. The salt is deliquescent and should be stored in a tightly stoppered container. Its solubility in H2O is 10% at room temperature and it is soluble in Me2CO. The free base reacts strongly alkaline in H2O. It has max 224nm ( 4000) in H2O. The picrate has m 252o (sintering at ~245o).
