Description

Niclosamide is a synthetic chlorinated salicylanilide compound with potent anthelmintic and molluscicidal properties. Its primary commercial value lies in its effectiveness as a broad-spectrum anti-parasitic agent, particularly against tapeworms and as a key component in molluscicide formulations for disease control. This product is essential for manufacturers in the pharmaceutical, veterinary medicine, and public health sectors, where it is used in the production of human and animal anthelmintic drugs and in programs to control schistosomiasis. Niclosamide CAS NO 50-65-7 is also gaining significant research interest for its potential repurposing in antiviral and anticancer applications.

Application

• Active Pharmaceutical Ingredient (API) in human anthelmintic medications for treating tapeworm infections.
• Key component in veterinary pharmaceutical formulations for deworming livestock and companion animals.
• Primary molluscicide in public health programs to control the snail vectors of schistosomiasis (bilharzia).
• Intermediate in the synthesis of more complex pharmaceutical compounds and agrochemicals.
• Research chemical for investigating novel biological activities, including antiviral and anticancer effects.
• Ingredient in piscicide formulations for managing parasitic infestations in aquaculture.
