Description

Levamisole is a versatile and potent chiral organic compound with significant pharmacological and agrochemical applications. Its primary value lies in its anthelmintic and immunomodulatory properties, making it a critical active ingredient for both human and veterinary medicine. This product is essential for manufacturers in the pharmaceutical, veterinary, and research sectors seeking a reliable, high-purity intermediate for API synthesis and formulation development.

Application

• Pharmaceutical API Intermediate: A key chiral building block in the synthesis of active pharmaceutical ingredients (APIs) for anthelmintic drugs.
• Veterinary Medicine: Used in the formulation of deworming treatments for livestock, poultry, and companion animals.
• Immunomodulation Research: Serves as a research chemical in immunological studies due to its ability to modulate immune system responses.
• Agrochemical Synthesis: Acts as a precursor or intermediate in the production of certain crop protection agents.
• Chemical Synthesis: Utilized as a chiral auxiliary or resolving agent in asymmetric synthesis for fine chemicals.
• Reference Standard: Supplied as a high-purity analytical standard for quality control and regulatory testing in laboratories.
