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.

Carbendazim
CAS:<p>Carbendazim is a fungicide that inhibits the growth of fungi and bacteria. It has been shown to be potent inducers of polymerase chain reaction (PCR) amplification, with a rate constant of 0.0103 per minute. Carbendazim also has a significant effect on electrochemical impedance spectroscopy (EIS). 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/molOmeprazole impurity F and G

CAS:<p>Albendazole sulfoxide is a sulfoxide of albendazole. The molecular docking analysis of the two molecules showed that the sulfoxide group is located in the same position as the hydroxyl group on albendazole. It has been shown that this replacement of hydroxyl with a sulfoxide group increases the solubility and stability of albendazole, which may be due to hydrogen bonding interactions between these groups. Albendazole sulfoxide has been shown to be an effective treatment for infections caused by parasites such as helminths. However, it should not be used in combination with drugs that are metabolized by cytochrome P450 enzymes because it can inhibit their activity.</p>Formula:C12H15N3O3SPurity:Min. 97 Area-%Color and Shape:White PowderMolecular weight:281.33 g/molMethyl 2,2-dithienylglycolate
