Tretyakov, Eugene V. et al. published their research in Mendeleev Communications in 1995 | CAS: 54210-32-1

1-Methyl-3-nitro-1H-pyrazole (cas: 54210-32-1) belongs to pyrazole derivatives. Pyrazole has two ring nitrogen atoms in which N1 is pyrrolic and N2 is pyridine-like. The N1 nitrogen is not reactive but is deprotonated in the presence of a base-forming anion. Pyrazole rings have been used as core components of several leading non-steroidal anti-inflammatory drugs (NSAIDs) and antihypertensive drugs. It has also been found to be useful as a bifunctional ligand for metal catalysis.Name: 1-Methyl-3-nitro-1H-pyrazole

Nitrodeiodination of polyiodopyrazoles: a convenient synthesis of 4-nitroiodopyrazoles was written by Tretyakov, Eugene V.;Vasilevsky, Sergei F.. And the article was included in Mendeleev Communications in 1995.Name: 1-Methyl-3-nitro-1H-pyrazole This article mentions the following:

A number of 3,4-, 4,5-diiodo- and 3,4,5-triiodo-1-methypyrazoles have been converted into the corresponding almost inaccessible 3-, 5-iodo- and 3,5-diiodo-1-methyl-4-nitropyrazoles by nitration with a HNO3-H2SO4 mixture In the experiment, the researchers used many compounds, for example, 1-Methyl-3-nitro-1H-pyrazole (cas: 54210-32-1Name: 1-Methyl-3-nitro-1H-pyrazole).
