Monensin History

The structure of Monensin (17090-79-8) was first described by Agtarap et al. in 1967, and was the first polyether antibiotic to have its structure elucidated in this way. The first total synthesis of momensin was reported by Kishi et al in 1979.

Monensin Uses

 Monensin (17090-79-8) is used extensively in the beef and dairy industries to increase the production of propionic acid, prevent coccidiosis and bloat.In addition, its derivatives monensin methyl ester (MME), and particularly monensin decyl ester (MDE) are widely used in ion selective electrodes.
