Description

Sulfamonomethoxine Sodium is a potent, long-acting sulfonamide antibiotic in its sodium salt form, offering enhanced water solubility for formulation. This compound is valued for its broad-spectrum antibacterial activity, making it a critical active pharmaceutical ingredient (API) in veterinary and aquaculture medicine. It is primarily required by manufacturers of veterinary pharmaceuticals and animal health products for the effective treatment and prevention of systemic bacterial infections.

Application

• Veterinary Pharmaceutical Formulations: Primary use as an active ingredient in injectable solutions, powders, and premixes for livestock (poultry, swine, cattle).
• Aquaculture and Fish Farming: Used in medicated feeds or bath treatments to control bacterial diseases in fish and shrimp.
• Treatment of Respiratory & Systemic Infections: Effective against pathogens causing pneumonia, septicemia, and other systemic bacterial diseases in animals.
• Coccidiostat Adjunct: Can be used in combination with other agents for managing coccidial infections in poultry.
• Research & Development: Serves as a reference standard and key intermediate in pharmaceutical R&D for new antibacterial agents.
• Feed Additive Production: Incorporated into nutritional supplements and prophylactic feed mixes for disease prevention in animal herds.

Quality Control

Our Sulfamonomethoxine Sodium is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for assay and related substances, to ensure it meets high-purity standards suitable for pharmaceutical use. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and residual solvent profiles 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, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture.
