Description

Levamisole Hydrochloride is a synthetic anthelmintic and immunomodulatory agent belonging to the chemical class of imidazothiazoles. Its primary commercial value lies in its dual functionality, serving as a critical active pharmaceutical ingredient (API) in veterinary and human medicine, as well as a key intermediate in advanced chemical synthesis. This compound is essential for manufacturers in the pharmaceutical, veterinary, and fine chemical industries seeking a reliable, high-purity raw material for producing antiparasitic formulations and research compounds.

Application

• Veterinary Anthelmintic Formulations: Primary use as an active ingredient in medications for treating parasitic worm (nematode) infections in livestock, poultry, and companion animals.
• Human Pharmaceutical Intermediates: Serves as a key building block in the synthesis of more complex pharmaceutical agents, particularly those targeting immune system regulation.
• Immunomodulatory Research: Used in biochemical and pharmacological research to study its effects on the immune system and cell-mediated immunity.
• Fine Chemical Synthesis: Acts as a chiral precursor or intermediate in the synthesis of specialized organic compounds for agrochemical and pharmaceutical development.
• Reference Standard: Supplied as a high-purity analytical standard for quality control testing in pharmaceutical manufacturing and regulatory compliance.
