Pyrantel pamoate is an anthelmintic drug used primarily to treat parasitic worm infections in humans and animals, including pinworms, roundworms, and hookworms. It works by paralyzing the worms’ nervous system, making them easy to expel from the body. This white to off-white powder has a CAS number of 22204-24-6, with the molecular formula C11H14N2S · C23H16O6 and a molecular weight of 594.68. It must be stored between 2–8°C and carries a **Danger** signal word due to its toxicity. Molekula supplies Pyrantel pamoate from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
