Abstract 3(5)-Diazonia-4-nitropyrazole hydrochloride, which readily undergoes nucleophilic substitution, is formed by diazotization of 3(5)-amino-4-nitropyrazole. Depending on the conditions, in the diazotization of 3,5-diamino-4-nitropyrazole one or both amino groups undergo reaction. Moreover, a nitro group is simultaneously replaced by a hydroxyl group, and the final product is 3,5-bisdiazo-4-pyrazolone.
