Application

3-Aminopyrazole was used in the spectroscopic characterization of ferrocenoyl peptides via 1H-NMR spectroscopy. It was also used in the synthesis of:
  • symmetrical dialkylpyrazolo[1,5-a]pyrimidines via condensation with symmetrical β-diketones
  • 3,4-annelated coumarins
  • heterocyclic compounds of pharmaceutical interest
  • pyrazolopyrimidines

General description

3-Aminopyrazole is a heteroarylamine.
