Oxfendazole

Oxfendazole (CAS 53716-50-0) is a benzimidazole anthelmintic developed for veterinary use, structurally related to fenbendazole but with a sulfoxide functional group. It exhibits broad-spectrum activity against gastrointestinal nematodes, lungworms, and certain cestodes, making it a staple in livestock and companion animal health programs. Our product is supplied as a white to off-white crystalline powder, with an HPLC purity of ≥99%, ensuring consistent performance in feed premixes and oral suspensions.

The compound works by binding to parasite tubulin, inhibiting microtubule polymerization, which disrupts glucose uptake and depletes energy stores. This mechanism is well-documented, and oxfendazole is often used as a reference standard in pharmaceutical research. We provide comprehensive documentation, including COA, MSDS, and TDS, per batch for regulatory compliance and quality assurance.

Synonyms: Fenbendazole sulfoxide, 5-(Phenylsulfinyl)-1H-benzimidazol-2-yl carbamic acid methyl ester, Oxfendazol, Oxfendazole (INN)
