Facile and environmentally friendly synthesis of nitropyrazoles using montmorillonite K-10 impregnated with bismuth nitrate was written by Ravi, P.;Tewari, Surya P.. And the article was included in Catalysis Communications in 2012.Recommanded Product: 3-Methyl-4-nitro-1H-pyrazole This article mentions the following:
Nitropyrazoles in higher yields were synthesized using montmorillonite K-10 impregnated with bismuth nitrate and the present procedure may be applied for the nitration of a wide variety of azoles in the drug and pharmaceutical industries. In the experiment, the researchers used many compounds, for example, 3-Methyl-4-nitro-1H-pyrazole (cas: 5334-39-4Recommanded Product: 3-Methyl-4-nitro-1H-pyrazole).
3-Methyl-4-nitro-1H-pyrazole (cas: 5334-39-4) belongs to pyrazole derivatives. The 1H-pyrazole provides an excellent means by which to provide the requisite hydrogen bond acceptor–donor motifs, whether as a monocyclic ring or as a fused indazole ring. Pyrazole the presence of this nucleus in pharmacological agents of diverse therapeutic categories such as celecoxib, a potent anti-inflammatory, the antidepressant agent fezolamide have proved the pharmacological potential of the pyrazole moiety. Recommanded Product: 3-Methyl-4-nitro-1H-pyrazole
