  • Applications

    Monensin (CAS 17090-79-8) is a polyether ionophore antibiotic used primarily in animal production as a feed additive to prevent coccidiosis in poultry and to improve feed efficiency in cattle, sheep, and other ruminants; it is typically supplied as premixes or medicated feeds under veterinary supervision. In practice, it acts as a coccidiostat and rumen modifier, modulating fermentation to enhance performance while controlling parasite loads. Beyond production agriculture, it is used in veterinary research and formulation development as an ionophore antibiotic tool to study membrane ion transport. Its use is regulated and limited by local regulations and formulation specifications, and it is not intended for human use.
