The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 1-Methyl-4-nitro-1H-imidazol-5-amine(SMILESS: NC1=C([N+]([O-])=O)N=CN1C,cas:4531-54-8) is researched.Application In Synthesis of 3,4-Dihydroisoquinoline. The article 《Solvatochromism of Heteroaromatic Compounds: XIV. 5-Amino-1-methyl-4-nitropyrazole and Its Analogs》 in relation to this compound, is published in Russian Journal of General Chemistry (Translation of Zhurnal Obshchei Khimii). Let’s take a look at the latest research on this compound (cas:4531-54-8).
The solvatochromism of H complexes of 5-amino-1-methyl-4-nitropyrazole and 2-nitroaniline derivatives in aprotic protophilic media was described on a quant. level with the aid of Kamlet-Taft empirical parameters. Specific solvation affects only one of the two long-wave bands, that corresponding to an electronic transition involving orbital electron d. transfer from the H-bound N atom. When such transfer does not occur, which is typical of the second transition, specific solvatochromic effect is either weak or absent.
In some applications, this compound(4531-54-8)Reference of 1-Methyl-4-nitro-1H-imidazol-5-amine is unique.If you want to know more details about this compound, you can contact with the author or consult more relevant literature.
