Benzimidazole and Imidazole Derivatives
Benzimidazole is a compound consisting of a benzene ring fused to an imidazole ring, a five-membered structure containing two nitrogen atoms. Benzimidazole derivatives, such as albendazole, are known for their antiparasitic and antifungal activity, used in the treatment of parasitic infections and certain parasitic diseases in animals and humans. Imidazole, on the other hand, is a five-membered structure with two nitrogen atoms found in various biologically active compounds. Imidazole derivatives, such as metronidazole, have antimicrobial and antiparasitic properties. These compounds are also used in the pharmaceutical industry for treating bacterial infections, parasitic diseases, and some fungal infections, as well as in organic chemistry as catalysts.
At CymitQuimica, we offer high-purity benzimidazoles and imidazoles for research in medicinal chemistry, pharmacology, and biotechnology.

CAS:<p>4-Isobutyl-2-pyrrolidinone is a colorless liquid that belongs to the category of phosphites. It has a high boiling point, which makes it suitable for use in organic solvents and as a heat transfer agent. The thermodynamic properties of 4-Isobutyl-2-pyrrolidinone have been evaluated using the protonation theory. It can be protonated at either the nitrogen or the methyl group, and both forms are present in solution. This means that 4-Isobutyl-2-pyrrolidinone is acidic and can react with other compounds to form salts called lactams. There are two isomers of this compound: cis and trans. Both isomers exist in equilibrium; however, the cis isomer predominates at room temperature.

The EIS analysis was used to compare carbendazim-treated cells with untreated cells, which showed that carbendazim causes an increase in the resistance across the cell membrane. This research suggests that carbendazim may be genotoxic, as it increased the amount of DNA damage observed in wild-type strains and altered the optical properties of DNA. Carbendazim is also an effective inhibitor of nitrite ion oxidation and colloidal gold deposition, which has led to its use as a water vapor control agent for plants.</p>Formula:C9H9N3O2Purity:Min. 95%Color and Shape:PowderMolecular weight:191.19 g/molN-Desmethyl galanthamine
