Description

Monensin is a polyether antibiotic ionophore widely recognized for its potent coccidiostatic and growth-promoting properties in ruminants. Its primary commercial value lies in its ability to modulate rumen fermentation, improving feed efficiency and promoting weight gain in beef and dairy cattle. This makes it an essential feed additive for the global animal nutrition and veterinary pharmaceutical industries. We supply high-purity Monensin CAS NO 17090-79-8 to manufacturers requiring reliable, consistent quality for their formulations.

Application

• Ruminant Feed Additive: Primary use as a coccidiostat and growth promotant in beef and dairy cattle feed.
• Poultry Coccidiosis Control: Used in specific formulations for the prevention of coccidiosis in poultry.
• Veterinary Pharmaceutical Ingredient: Active pharmaceutical ingredient (API) in premixes and medicated feeds.
• Metabolism Modifier: Shifts rumen fermentation patterns to increase propionate production, enhancing feed efficiency.
• Research & Development: Standard for microbiological and biochemical research involving ionophores and antibiotic mechanisms.
• Comparative Studies: Used as a reference compound in the development of novel antibiotic and feed additive products.

Quality Control

Our Monensin is manufactured under strict quality systems to ensure it meets the stringent requirements of the animal health industry. Each batch is tested to confirm identity, purity, and potency, with specifications aligning with relevant agricultural and feed-grade standards. A comprehensive Certificate of Analysis (COA) documenting all test results is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed and away from direct light and moisture to maintain stability and potency.
