Used in the preparation of heterocyclic compounds of pharamaceutical interest.

3-aminopyrazole is an organic intermediate, which can be reduced from nitro pyrazole, or 3 (5) -aminopyrazole 4-formic acid can be prepared by cyclization of ethyl ethoxymethylene cyanoacetate and hydrazine hydrate, and then decarboxylated. 3- aminopyrazoles can be used as pharmaceutical intermediates, used for the preparation of drug-related heterocyclic compounds, used for the synthesis of pyrazoles and pyrimidines by one-pot method.
