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.

This molecule has been used in the synthesis of a number of drugs, including thiopental, a barbiturate that is used as an anaesthetic. Di-2-thienylmethanone is also the precursor for the synthesis of fluoroquinolones, which are potent antibacterial agents. The Friedel-Crafts reaction is one way this molecule is synthesized, and it involves the addition of an alkyl halide to an unsaturated double bond. This reaction is named after Charles Friedel and James Crafts who first discovered it in 1877.</p>Formula:C9H6OS2Purity:Min. 95%Color and Shape:White PowderMolecular weight:194.28 g/molCarbendazim
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/mol4-Desmethoxy omeprazole sulfide
