Description

Sulfamethazine is a synthetic sulfonamide antibacterial agent widely used in veterinary medicine. This compound is valued for its efficacy against a broad spectrum of gram-positive and gram-negative bacteria, making it a critical component in animal health management. It is primarily utilized by manufacturers in the veterinary pharmaceutical and animal feed additive industries to formulate treatments and prophylactics for livestock.

Application

• Veterinary Pharmaceuticals: A key active ingredient in injectable solutions, boluses, and oral suspensions for treating bacterial infections in cattle, swine, and poultry.
• Feed Additives: Incorporated into medicated animal feeds for disease prevention and growth promotion at therapeutic or sub-therapeutic levels.
• Aquaculture: Used in the treatment of bacterial diseases in farmed fish and shellfish.
• Companion Animal Medicine: Formulated into medications for dogs and cats, particularly for urinary tract and respiratory infections.
• Research & Development: Serves as a reference standard and biochemical tool in microbiological and pharmacological research.
• Intermediate Synthesis: Acts as a chemical intermediate in the synthesis of more complex sulfonamide derivatives.
