Pharmaceutical Grade Levamisole Hydrochloride CAS 16595-80-5 Anthelmintic API & Immunomodulator Raw Material

Levamisole Hydrochloride (Abbr: Levamisole HCl, CAS:16595-80-5,EINECS:240-654-6, HS Code:2934999090) is a white to off-white crystalline powder, an imidazothiazole derivative with broad-spectrum anthelmintic and immunomodulatory activity. We supply pharmaceutical grade, veterinary grade and technical grade products complying with USP, EP, BP and international quality standards. It is freely soluble in water and soluble in ethanol, with stable chemical properties and high oral bioavailability. As a classic high-efficiency low-toxicity deworming agent, it is widely used in human medicine, animal husbandry, aquaculture and biological research fields.

Applications
Veterinary & Animal Health (Core Application)
Broad-spectrum anthelmintic for livestock, poultry and pets. It effectively paralyzes and expels roundworms, hookworms, pinworms and other gastrointestinal nematodes in swine, cattle, sheep, poultry and dogs, with high efficacy and low side effects. It also enhances animal immune function and improves disease resistance in intensive farming.
Human Pharmaceutical Field
Used as a clinical oral anthelmintic for the treatment of ascariasis, ancylostomiasis and enterobiasis. It also serves as an immunoadjuvant to assist in chronic infection management, autoimmune disease regulation and tumor adjuvant therapy, with a long history of safe clinical application.
Aquaculture Industry
Applied in fish, shrimp and frog farming to control parasitic nematode infections, reduce parasite-caused mortality, and improve aquatic product survival rate and breeding efficiency. It also exerts a mild immunomodulatory effect on farmed aquatic animals.
Biological & Medical Research
Widely used as a tool reagent in immunology research, cell culture experiments and pharmacological studies. It is a standard reference material for pharmaceutical analysis, and commonly applied in immune regulation, anti-infection mechanism and tumor immunology studies.
Fine Chemical Intermediate
Key intermediate for synthesizing other anthelmintic drugs, immunomodulators and fine chemical products. Its mature synthesis process and stable quality make it an important raw material in the fine chemical and pharmaceutical production chain.
Feed Additive Field
Added to compound feeds at low dosage for routine parasite prevention in livestock and poultry breeding. It reduces parasite infection rates, improves nutrient absorption efficiency, and promotes animal growth and production performance.
