Description

Pyrvinium Pamoate is a quaternary ammonium salt known for its distinctive orange-red color and potent anthelmintic properties. This compound is of significant commercial and research interest due to its primary historical use as an anti-parasitic agent and its emerging potential in oncology research. It is a critical material for pharmaceutical manufacturers, research institutions, and developers of active pharmaceutical ingredients (APIs).

Application

• Pharmaceutical API Manufacturing: Serves as the active ingredient in formulations for the treatment of parasitic infections, particularly pinworm (enterobiasis).
• Biomedical Research: Investigated for its role as a selective inhibitor of the Wnt/β-catenin signaling pathway, making it a valuable tool compound in cancer biology and stem cell research.
• Reference Standard: Used as a certified reference material (CRM) in analytical laboratories for method development, validation, and quality control testing of pharmaceutical products.
• Veterinary Medicine: Potential application in the development of anti-parasitic treatments for animals.
• Chemical Intermediate: Utilized in the synthesis of more complex molecules for pharmacological evaluation.
