Application

4-Nitrophenyl isocyanate can be used as a reactant to synthesize:
  • 4-aminophenyl carbamic acid methyl ester by Raney nickel catalyzed hydrogenation in methanol-DCM solvent system.
  • Urea-functionalized derivatives with p-nitrobenzene units by reacting with 1,2-bis(2′-aminophenoxy) benzene.
  • 2-(5-methyl-3,4-diphenyl-1H-pyrrole-2-carbonyl)-N-(4-nitrophenyl)hydrazinecarboxamide by treating with 5-methyl-3,4-diphenyl-1H-pyrrole-2-carbohydrazide.
