General Information

Albendazole Impurities and Albendazole 

Daicel Pharma is a reliable source for synthesizing high-quality Albendazole impurities, specifically Albendazole impurity (Albendazole EP Impurity-H), Albendazole sulfoxide (Albendazole EP impurity B), Albendazole sulfone (Albendazole EP impurity C), and more. These impurities help assess the quality, stability, and safety of the active pharmaceutical ingredient, Albendazole. Daicel Pharma also offers custom synthesis of Albendazole impurities, which can be shipped worldwide to meet customers’ unique requirements.

Albendazole [CAS: 54965-21-8] is a broad-spectrum drug. It is a synthetic benzimidazole-derivative anthelmintic, which can kill many parasitic worms in the body. It treats echinococcosis, a parasitic worm that forms cysts in the liver and lungs.

Albendazole: Use and Commercial Availability  

Albendazole is an antiparasitic medication approved by the US FDA for treating specific parasitic worm infections. It treats microsporidiosis, which can be an opportunistic infection (OI) of HIV. Albendazole is available under various brand names. As an antihelminthic medication, Albendazole can treat several parasitic worm infections. It treats cystic hydatid disease in the liver, lungs, and peritoneum caused by Echinococcus granulosus. It also treats neurocysticercosis caused by larval forms of the pork tapeworm, Taenia solium.

Albendazole Structure and Mechanism of Action

The chemical name of Albendazole is Methyl 5-propylthio-2-benzimidazolecarbamate. Its chemical formula is C₁₂H₁₅N₃O₂S, and its molecular weight is approximately 265.33 g/mol.

The anthelmintic activity of Albendazole is due to its metabolite, albendazole sulfoxide. It inhibits the formation of microtubules from tubulin, thus interfering with the reproduction and survival of helminths.

Albendazole Impurities and Synthesis

During the manufacturing process of Albendazole, impurities may form that can potentially reduce its efficacy or cause harm to patients. These impurities can arise from various sources, including starting materials, intermediates, and reagents used in the synthesis¹ of Albendazole. Therefore, it is essential to control and monitor impurities to ensure the safety and effectiveness of the drug.

Daicel Pharma provides a Certificate of Analysis (CoA) for Albendazole impurity standards, which includes Albendazole impurity (Albendazole EP Impurity-H), Albendazole sulfoxide (Albendazole EP impurity B), Albendazole sulfone (Albendazole EP impurity C), and more. The CoA is from an analytical facility that adheres to current Good Manufacturing Practices (cGMP) and includes complete characterization data, such as 1H NMR, 13C NMR, IR, MASS, and HPLC purity2. We give additional characterization data such as 13C-DEPT and CHN on request. Daicel Pharma can also generate unknown Albendazole impurities or degradation products and provide labeled compounds to assess the effectiveness of Albendazole. Further, Daicel Pharma offers Albendazole-D3 (methoxy-D3), a deuterium-labeled Albendazole compound used in bio-analytical research, such as BA/BE studies. A complete characterization report is a part of each delivery.
