Description

Sulfamethazine Sodium Salt is the sodium salt derivative of the sulfonamide antibiotic sulfamethazine, offering enhanced water solubility for formulation. This compound is a critical intermediate in the production of veterinary and pharmaceutical products, valued for its antibacterial efficacy against a broad spectrum of microorganisms. It is primarily required by manufacturers in the animal health, pharmaceutical synthesis, and research and development sectors for creating injectable solutions, medicated feeds, and analytical standards.

Application

• Veterinary Pharmaceutical Formulations: Key active ingredient in injectable antibiotics for livestock, poultry, and companion animals to treat systemic bacterial infections.
• Medicated Feed Premixes: Incorporated into animal feed for prophylactic and therapeutic purposes to promote herd health and growth.
• Pharmaceutical Intermediate: Serves as a crucial building block in the synthesis of more complex sulfonamide-based drug substances.
• Research & Development: Used as a reference standard in analytical laboratories for method development, quality control, and pharmacokinetic studies.
• Aquaculture: Applied in fish farming to control bacterial diseases, often formulated for water dispersion or oral administration.
