Dérivés du Benzimidazole et de l’Imidazole
Le benzimidazole est un composé constitué d’un noyau benzénique fusionné à un noyau imidazole, une structure à cinq membres contenant deux atomes d’azote. Les dérivés du benzimidazole, comme l’albendazole, sont connus pour leur activité antiparasitaire et antifongique, utilisés dans le traitement des infections parasitaires et de certaines maladies parasitaires chez les animaux et les humains. L’imidazole, quant à lui, est une structure à cinq membres avec deux atomes d’azote, présente dans divers composés biologiquement actifs. Les dérivés de l’imidazole, comme le métronidazole, possèdent des propriétés antimicrobiennes et antiparasitaires. Ces composés sont également utilisés dans l’industrie pharmaceutique pour le traitement des infections bactériennes, des maladies parasitaires et de certaines infections fongiques, ainsi qu’en chimie organique comme catalyseurs.
Chez CymitQuimica, nous proposons des benzimidazoles et des imidazoles de haute pureté pour la recherche en chimie médicinale, pharmacologie et biotechnologie.

CAS :<p>Pantoprazole sulfone N-oxide is a prodrug that is converted to the active form pantoprazole in the stomach where it inhibits gastric acid secretion. Pantoprazole sulfone N-oxide has been shown to be genotoxic, and can cause polyvinyl chloride to degrade when stored together. Reconstituted solution of this drug should be used within 24 hours after reconstitution, as the chemical stability of this drug decreases rapidly. Validation studies have been conducted on different analytical methods for determining pantoprazole concentrations in reconstituted solutions, and these methods have been harmonized with those published by the United States Pharmacopeia (USP). The pump inhibitor activity of pantoprazole sulfone N-oxide has been demonstrated in dogs, and it is also useful for treating acid reflux disease in humans. Pantoprazole sulfone N-oxide is unstable at high temperatures (>25°C), so should not be refrigerated or</p>Formule :C16H15F2N3O6SDegré de pureté :Min. 95%Masse moléculaire :415.37 g/molAlbendazole impurity F

CAS :<p>Carbamazepine is a drug that has been used to treat epileptic seizures and trigeminal neuralgia. Impurities in the drug are removed by using chromatographic methods, such as high-performance liquid chromatography (HPLC). The rotarod test is an animal model of motor coordination and balance that can be used to assess the effects of drugs on these functions. Carbamazepine impurities may cause depression and have an epileptic effect on animals. Chronic exposure to carbamazepine can lead to drug reactions and gene polymorphisms, which may alter the metabolism of the drug. Analytical methods for determining carbamazepine impurities include HPLC, gas chromatography mass spectrometry (GC-MS), and thin-layer chromatography (TLC).</p>Formule :C15H14N2ODegré de pureté :Min. 95%Masse moléculaire :238.28 g/mol(R,R)-Solifenacin succinate
