Polarographic investigations in the imidazole and thiazole series. Nitro derivatives, aldehydes, and halogen derivatives was written by Laviron, E.. And the article was included in Abhandl. Deut. Akad. Wiss. Berlin, Kl. Chem., Geol. Biol. in 1964.Application of 3034-41-1 This article mentions the following:
4-(5)-Nitroimidazole,-2-nitroimidazole, 4-nitro- and 5-nitro-l-methylimidazole, and 4-(5)nitro-1,3-dimethylimidazolium iodide (I) are reduced in 2 steps, but the 2nd step is not equally sharp in all cases. Ε1/2 is a linear function of pH for 2- nitroimidazole and I but not for the other compounds The diffusion current of 2-nitroimidazole is diminished at low pH. This is also true of the 5-nitro derivatives of thiazole (with NH2, NHAc, Cl, Br, or OH substituted in position 2). 4(5)-Imidazolecarboxaldehyde and thiazolecarboxaldehyde in buffered aqueous and in absolute EtOH and MeOH solutions, acidified with H2SO4 or buffered with acetate and HOAc, show a marked lowering of the diffusion current in acid medium. This was ascribed to a polarographically irreducible hydrate of the imidazolium or thiazolium ion in acid, a hypothesis that was further supported by uv spectra. Of numerous halogen derivatives investigated, all compounds in the thiazol series are very easily reducible, while only the 2-iodo and 2,4,5-triiodo compounds give well defined waves in the imidazole series. At the extremes of pH, the Ε1/2 of the halogen derivatives are independent of pH, while a more or less linear dependence on pH (with varying slope) is found for intermediate values of pH. In the experiment, the researchers used many compounds, for example, 1-Methyl-4-nitroimidazole (cas: 3034-41-1Application of 3034-41-1).
1-Methyl-4-nitroimidazole (cas: 3034-41-1) belongs to imidazole derivatives. Imidazole is a heterocyclic compound with a five-membered planar ring. It is amphoteric and highly polar. Many drugs contain an imidazole ring, such as certain antifungal drugs, the nitroimidazole series of antibiotics, and the sedative midazolam.Application of 3034-41-1
