What is 1-PHENYLSEMICARBAZIDE?
The Uses of 1-PHENYLSEMICARBAZIDE
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.
What are the applications of Application
1-Phenylsemicarbazide is A useful biochemical for proteomics research
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 It has been withdrawn in at least one country on grounds of its adverse effect profile and it appears to have fallen into disuse in others.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.]
