Description

General description

3-Aminopyrazole is a heteroarylamine.

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
