Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Material und Organismen called Toxicity of imidazole derivatives to selected fungi of the classes Ascomycetes and Deuteromycetes, Author is Gajdzinski, Maciej; Mroczkiewicz, Andrzej, which mentions a compound: 4897-25-0, SMILESS is C1=NC(=C(Cl)[N]1C)[N+]([O-])=O, Molecular C4H4ClN3O2, Reference of 5-Chloro-1-methyl-4-nitroimidazole.
The lowest concentrations of imidazole derivatives that showed fungicidal effects on 5 selected mold fungi (Ascomycetes and fungi imperfecti) were determined by the agar plate method. Those imidazole derivatives that had halo and a NO2 group on the ring were the most toxic towards these fungi. 5-Chloro-1-methyl-4-nitroimidazole [4897-25-0] was particularly toxic; quantities of 600-1000 ppm added to the nutrient agar completely inhibited growth.
The article 《Toxicity of imidazole derivatives to selected fungi of the classes Ascomycetes and Deuteromycetes》 also mentions many details about this compound(4897-25-0)Reference of 5-Chloro-1-methyl-4-nitroimidazole, you can pay attention to it, because details determine success or failure
