Used as an active metabolite of mebendazole, it contributes to the anthelmintic effect by disrupting microtubule formation in parasitic worms, leading to parasite death. It is involved in the treatment of intestinal worm infections, including pinworm, roundworm, and hookworm. Due to its mode of action, it shows potential in research related to antiparasitic drug development and has been studied for possible repurposing in antitumor applications, where it may inhibit cancer cell proliferation by similar microtubule interference mechanisms.
