| Hazard Information | Back Directory | [Uses]
1-Phenylsemicarbazide was used in the synthesis of a series of alkyl(aryl/heteroaryl) substituted 3-trifluoromethyl-1H-1-phenylpyrazoles and alkyl 3-carboxylate analogs by the cyclocondensation reactions with 4-alkoxy-1,1,1-trihaloalk-3-en-2-ones. | [Definition]
ChEBI: Phenicarbazide is a member of phenylhydrazines. | [Brand name]
Antipyretic dellepsoids d26. | [World Health Organization (WHO)]
Phenicarbazide, which has analgesic and antipyretic activity, was
introduced in the 1970s. It has been withdrawn in at least one country on grounds
of its adverse effect profile and it appears to have fallen into disuse in others. | [Purification Methods]
Crystallise it from water and dry it in a vacuum over KOH. [Beilstein 15 H 287, 15 II 106, 15 III 184, 15 IV 180.] |
