3-Amino-5-phenylpyrazole Usage And Synthesis
Chemical PropertiesOff-white to cream colored crystalline powder
Uses3-Amino-5-phenylpyrazole ((3-phenyl-1H-pyrazol-5-amine) may be used in the synthesis of the following:
  • Urea derivatives by reaction with azido(6-(benzofuran-2-yl)-2-methylpyridin-3-yl) methanone.
  • 2-Mercaptoacetamide analogs by treating with thioglycolic acid.
  • 3-(Substituentpyrimidayl)-5,6-benzocoumarins by treating with 3-(2′-formyl-1′-chlorovinyl)-5,6-benzocoumarin.
  • Substituted 2,7-diphenylpyrazolo[1,5-a]pyrimidine-5-carboxylic esters by reacting with substituted β-diketo esters.
  • N-ethoxycarbonylthiourea derivative by reacting with ethoxycarbonyl isothiocyanate.
  • Heterobiaryl pyrazolo[3,4-b]pyridines by reacting with indole-3-carboxaldehyde.
General Description3-Amino-5-phenylpyrazole (3-phenyl-1H-pyrazol-5-amine), an amino pyrazole derivative, is an aza-heterocyclic amine. It has been reported to be synthesized by heating either 3-amino-4-bromo- or 3-amino-5-phenylisothiazole in the presence of anhydrous hydrazine. On reaction with ZnCl2 it affords chlorido-tris(3-amino-5-phenyl-1Hpyrazole-N2)zinc (II) chloride.
