1. Chemical Name: methyl (5-propylsulfinyl-3H-benzoimidazol-2-yl)aminoformate 2. Molecular Formula:C12H15N3O3S 3. CAS No.:54029-12-8 4. Pharmacodynamic Properties: After albendazole(ABZ) is administered, intestinal and hepatic albendazole metabolism leads to albendazole sulfoxide (active metabolite) and albendazole sulfone (inactive metabolite) formation. The metabolism albendazole sulfoxide effects as the active substance against the worms, albendazole sulfone has no active affection. Therefore albendazole sulfoxide anthelmintic function is better than albendazole. 5. Storage: Keep container tightly closed in a cool, well-ventilated area. 6. Specification: CP(V)
