Description

Luxabendazole CAS NO 90509-02-7 is a high-purity benzimidazole anthelmintic compound. It is valued for its potent and broad-spectrum activity against parasitic worms, making it a critical active pharmaceutical ingredient (API) in veterinary and research applications. This product is essential for manufacturers developing antiparasitic formulations for livestock, companion animals, and for use in pharmacological studies.

Application

• Veterinary Pharmaceutical API: Primary active ingredient in oral drenches, pastes, and injectables for livestock (cattle, sheep, goats) and companion animals.
• Broad-Spectrum Anthelmintic: Effective against gastrointestinal nematodes, lungworms, and certain tapeworms.
• Research & Development: Used as a reference standard and building block in pharmacological research for new antiparasitic agents.
• Feed Additive Premixes: Incorporated into medicated feed for herd-level parasite control programs.
• Generic Drug Manufacturing: Serves as the core API for producing generic versions of established benzimidazole-based anthelmintics.
