Benzimidazole and Imidazole Derivatives

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.
