Description

Levamisole is a synthetic anthelmintic and immunomodulatory agent of the imidazothiazole class. It is a critical active pharmaceutical ingredient (API) valued for its broad-spectrum efficacy against parasitic nematodes in both human and veterinary medicine. This compound is essential for manufacturers in the pharmaceutical and animal health sectors, where it is formulated into tablets, injectables, and feed additives. Our supply of Levamisole CAS NO 49548-36-9 meets the stringent quality requirements for these demanding applications.

Application

• Human Anthelmintic Formulations: Used in the production of tablets for treating roundworm (Ascaris) and hookworm infections.
• Veterinary Anthelmintics: A key component in drenches, injectables, and feed premixes for livestock, including cattle, sheep, goats, and swine, to control gastrointestinal nematodes.
• Immunomodulatory Research: Employed in clinical and preclinical research due to its ability to restore depressed immune function.
• Aquaculture: Used in certain regions for the treatment of parasitic infestations in fish farming.
• Pharmaceutical Intermediates: Serves as a chiral building block or precursor in the synthesis of more complex pharmaceutical compounds.
