1-Methyl-4-nitroimidazole (cas: 3034-41-1) belongs to imidazole derivatives. Many natural products, especially alkaloids, contain the imidazole ring. These imidazoles share the 1,3-C3N2 ring but feature varied substituents. Imidazole is incorporated into many important biological compounds. The most pervasive is the amino acid histidine, which has an imidazole side-chain. Histidine is present in many proteins and enzymes, e.g. by binding metal cofactors, as seen in hemoglobin.Synthetic Route of C4H5N3O2

Inexpensive Radical Methylation and Related Alkylations of Heteroarenes was written by Huang, Qi;Zard, Samir Z.. And the article was included in Organic Letters in 2018.Synthetic Route of C4H5N3O2 This article mentions the following:

A simple method for the introduction of a Me and higher aliphatic group to various heteroarenes using very inexpensive reagents is described. It is based on the radical addition of a carboxylic xanthate followed by decarboxylation. Depending on the heteroarene structure, the decarboxylation can be spontaneous or induced by heating in N,N-dimethylacetamide or N-Me pyrrolidone in a microwave oven. In the experiment, the researchers used many compounds, for example, 1-Methyl-4-nitroimidazole (cas: 3034-41-1Synthetic Route of C4H5N3O2).
