Description

Narasin CAS NO 58331-17-2 is a polyether ionophore antibiotic derived from *Streptomyces aureofaciens*. This compound is critically important for its potent anticoccidial and antibacterial activity, primarily targeting gram-positive bacteria. It is an essential feed additive in the poultry industry for the prevention of coccidiosis, promoting animal health and growth efficiency. Its application extends to veterinary medicine and as a research tool in microbiological studies.

Application

• Poultry Feed Additive: Primary use as an anticoccidial agent to control and prevent coccidiosis in broiler chickens.
• Veterinary Medicine: Used in formulations for the treatment of specific bacterial infections in livestock.
• Animal Growth Promoter: Enhances feed efficiency and promotes growth in production animals at approved levels.
• Microbiological Research: Serves as a selective agent in research laboratories to study ion transport and antibiotic mechanisms.
• Feed Premix Manufacturing: A key active ingredient in the production of concentrated medicated feed premixes.
• Comparative Studies: Used as a reference standard in analytical and efficacy studies against other ionophores.

Quality Control

Our Narasin is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot is tested to meet relevant specifications for feed-grade and research-grade materials. A comprehensive Certificate of Analysis (COA) detailing purity, potency, and impurity profiles is provided with every shipment to guarantee regulatory compliance and product integrity for your applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to minimize exposure to moisture. Keep away from incompatible materials.
