An antiprotozoal, it is used as the sodium salt as a feed additive for the prevention of coccidiosis in poultry and as a growth promoter in cattle. It has a role as a coccidiostat, an antifungal agent and an ionophore. It is a monocarboxylic acid, a cyclic hemiketal, a spiroketal and a polyether antibiotic."}]
