Product Overview
Niclosamide (CAS 50-65-7) is a salicylanilide-derived anthelmintic and molluscicide. It appears as a yellowish-white crystalline powder, odorless and tasteless. As a broad-spectrum parasiticide with strong biological activity, it is widely used in pharmaceutical anthelmintics, agricultural mollusc control, aquaculture and public health pest management. Manufactured via professional synthesis and recrystallization, it features high purity, low impurities and stable batch consistency. For legitimate pharmaceutical, agricultural and industrial use only.
Product Features
- High Purity: ≥98.0% (HPLC), meets pharmaceutical and agricultural grade standards.
- Broad-Spectrum Activity: Effective against tapeworms, liver flukes and snails (intermediate hosts of schistosomiasis).
- Low Water Solubility: Stable in aqueous environments, suitable for slow-release formulations.
- Strict QC: Full batch testing; standard COA and MSDS available on request.
Physical & Chemical Properties

Applications
- Pharmaceutical Industry: Classic anthelmintic for treating tapeworm infections (beef/pork tapeworm) in humans and animals.
- Agriculture: Molluscicide for controlling apple snails (Pomacea canaliculata) in rice fields.
- Public Health: Kills freshwater snails (intermediate hosts of schistosomiasis) to prevent disease transmission.
- Aquaculture: Piscicide to eliminate unwanted fish before restocking ponds.
- Research: Investigational antitumor and antiviral agent (inhibits STAT3 signaling).
Usage Restriction: For industrial, agricultural and pharmaceutical use only. Prohibited for illegal use and human consumption beyond medical indications.
