1. Chemical Name: methyl N-[5-(benzenesulfinyl)-3H-benzoimidazol-2-yl]carbamate 2. Molecular Formula:C15H13N3O3S 3. CAS No.: 53716-50-0 4. Pharmacodynamic Properties: Oxfendazole, the sulfoxide form of fenbendazole, is a broad spectrum benzimidazole anthelmintic. Oxfendazole acts by destroying the microtubular structure in the intestinal epithelium of helminths thus inhibiting the uptake of glycogen from the intestine of the parasite. Oxfendazole is effective in the treatment and control of adult and immature gastro-intestinal roundworms and lungworms (including Ostertagia, Haemonchus, Trichostrongylus, Nematodirus, Cooperia, Capillaria, Oesphagostomum, Chabertia, Trichuris and Dictyocaulus) for sheep, cattle, goats, and swine. It is also effective against roundworm eggs and tapeworms (Moniezia, head and segments). 5. Storage: Keep container tightly closed in a cool, well-ventilated area. 6. Specification: BPV/EP/CP(V)
