Description

Monensin B is a polyether ionophore antibiotic belonging to the monensin family, widely recognized for its potent coccidiostatic and growth-promoting properties. Its primary commercial value lies in its efficacy against a broad spectrum of Gram-positive bacteria and protozoa, making it a critical component in animal health and nutrition. This product is essential for manufacturers in the veterinary pharmaceutical and animal feed additive industries seeking to enhance livestock productivity and manage enteric diseases.

Application

• Veterinary Anticoccidial Agent: A key active ingredient in medicated feed and premixes for the prevention and control of coccidiosis in poultry, cattle, and swine.
• Ruminant Growth Promoter: Used in feedlot cattle to improve feed efficiency, promote weight gain, and alter rumen fermentation towards more propionate production.
• Antibacterial Agent: Effective against certain Gram-positive bacteria, utilized in research and development of antimicrobial formulations.
• Biochemical Research: Serves as a research tool in studies of ion transport across biological membranes and as a sodium ionophore in laboratory experiments.
• Feed Additive Intermediate: Employed as a high-purity intermediate for the synthesis of other monensin salts and derivatives in specialty feed supplements.

Quality Control

Our Monensin B is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for potency and related substances, to meet stringent specifications for use in animal health applications. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which may affect stability and handling properties.
