Description

Sulfadimethoxine Sodium Salt CAS NO 1037-50-9 is the sodium salt form of the long-acting sulfonamide antibiotic, sulfadimethoxine. This formulation offers enhanced water solubility, making it a critical active pharmaceutical ingredient (API) for veterinary and aquaculture applications. It is primarily utilized by manufacturers in the animal health and pharmaceutical industries for the formulation of injectable solutions, oral suspensions, and medicated feed premixes to combat bacterial infections.

Application

• Veterinary Pharmaceutical Formulations: Primary use in injectable and oral solutions for the treatment of respiratory, gastrointestinal, and systemic bacterial infections in livestock (cattle, swine, poultry) and companion animals.
• Aquaculture and Fish Farming: Used in medicated feeds or bath treatments to control bacterial diseases such as furunculosis in salmonids and other bacterial infections in farmed fish.
• Medicated Feed Premixes: Incorporated into animal feed for prophylactic or therapeutic purposes to maintain herd health and prevent disease outbreaks.
• Research and Development: Serves as a reference standard and key intermediate in pharmaceutical R&D for developing new antibacterial agents and studying sulfonamide resistance.
• Poultry Coccidiostat Adjunct: Used in combination with other agents for the control of coccidiosis in poultry, leveraging its antibacterial properties.
