| Cyanoacetohydrazide Usage And Synthesis |
Chemical Properties | BROWN GRANULAR CRYSTALLINE POWDER | Uses | 2-Cyanoacetohydrazide is used in the study of the viral inhibiting activity of some potential antiviral agents. | Purification Methods | Crystallise the hydrazide from EtOH. The hydrochloride has m 178-180o and the benzylidene derivative has m 178o. It is converted to 3-oxo-5-iminopyrazolidine in hot 40% aqueous NaOH. [Beilstein 2 H 591, 2 I 256, 2 III 1636.] IRRITANT. |
