Description

Tetramisole is a versatile chiral organic compound primarily known for its anthelmintic properties and role as a key intermediate in pharmaceutical synthesis. Its significance lies in its stereochemistry, with the levo-isomer, levamisole, being a widely recognized active pharmaceutical ingredient (API). This product is essential for manufacturers and research institutions in the pharmaceutical, veterinary medicine, and agrochemical sectors seeking a reliable building block for active ingredient development.

Application

• Pharmaceutical Intermediate: A critical precursor in the synthesis of the API levamisole, used historically as an immunomodulator and anthelmintic agent.
• Veterinary Anthelmintic: Serves as a base compound for formulating broad-spectrum deworming treatments for livestock and companion animals.
• Agrochemical Research: Investigated for potential applications in crop protection due to its biological activity against certain pests.
• Chemical Synthesis: Used as a chiral auxiliary or building block in asymmetric synthesis for creating more complex molecular structures.
• Biochemical Research: Employed in laboratory studies to investigate cell-mediated immunity and enzymatic processes.
• Reference Standard: Sourced by analytical laboratories for use as a high-purity standard in quality control and method development.
