Mebendazole is a broad-spectrum anthelmintic used primarily to treat parasitic worm infections, including ascariasis, trichuriasis, and hookworm infections. It works by inhibiting microtubule formation in parasites, leading to their immobilization and eventual death. This chemical is available with a CAS number of 31431-39-7, a molecular formula of C16H13N3O3, and a molecular weight of 295.2927 g/mol. It should be stored at ambient conditions and handled with care, as it carries a "Danger" signal word. Molekula supplies Mebendazole from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
