1-PHENYLSEMICARBAZIDE Usage And Synthesis
Uses1-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.
DefinitionChEBI: Phenicarbazide is a member of phenylhydrazines.
Brand nameAntipyretic 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 It has been withdrawn in at least one country on grounds of its adverse effect profile and it appears to have fallen into disuse in others.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 MethodsCrystallise it from water and dry it in a vacuum over KOH. [Beilstein 15 H 287, 15 II 106, 15 III 184, 15 IV 180.]
