Description

Roxarsone CAS NO 121-19-7 is an organoarsenic compound historically used as a feed additive in the poultry industry. Its primary commercial value was derived from its role in promoting growth, improving feed efficiency, and controlling coccidiosis. This product was primarily utilized by animal nutrition and feed manufacturing sectors, though its use is now heavily restricted or banned in many regions due to environmental and health concerns regarding arsenic residues.

Application

• Historical Poultry Feed Additive: Used to enhance growth rates and improve feed conversion efficiency in broiler chickens.
• Coccidiostat: Assisted in the prevention and control of coccidial intestinal parasites in poultry.
• Pigment Enhancer: Contributed to improved skin and egg yolk coloration in poultry.
• Research & Development: Serves as a reference standard and chemical intermediate in analytical, environmental, and toxicological research.
• Chemical Synthesis: Acts as a precursor or intermediate in specialized organic synthesis involving organoarsenic compounds.

Quality Control

Our Roxarsone is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as assay, impurity profile, and loss on drying. We adhere to relevant industry standards for laboratory reagents and research chemicals.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture.
