Description

Rafoxanide CAS NO 22662-39-1 is a halogenated salicylanilide derivative with potent anthelmintic properties. This compound is valued for its high efficacy against specific parasitic infections, particularly in veterinary medicine. It is a critical active pharmaceutical ingredient (API) for manufacturers developing treatments for the livestock and animal health industries.

Application

• Veterinary Anthelmintic Formulations: Primary use as an active ingredient in drenches, boluses, and feed additives for livestock.
• Control of Liver Fluke (Fasciola hepatica): Specifically effective against mature and immature stages of this parasitic flatworm in sheep, cattle, and goats.
• Broad-Spectrum Parasite Control: Used in combination with other anthelmintics for comprehensive parasite management programs.
• Pharmaceutical Intermediates: Serves as a key chemical intermediate in the synthesis of more complex veterinary pharmaceutical compounds.
• Research & Development: Utilized in biochemical and pharmacological studies related to parasite metabolism and anthelmintic drug discovery.
