Description

Sulfamethazine is a synthetic sulfonamide antibacterial agent widely used in veterinary medicine. Its primary value lies in its efficacy against a broad spectrum of Gram-positive and Gram-negative bacteria, making it a cornerstone for animal health and productivity. This compound is essential for manufacturers in the veterinary pharmaceutical and animal feed additive industries, where it is formulated for the prevention and treatment of various bacterial infections in livestock and poultry.

Application

• Veterinary Pharmaceuticals: Primary active ingredient in injectable solutions, boluses, and oral powders for treating bacterial infections in cattle, swine, poultry, and sheep.
• Feed Additives: Incorporated into medicated animal feeds for growth promotion and disease prophylaxis at sub-therapeutic levels.
• Aquaculture: Used in the treatment of bacterial diseases in farmed fish and shellfish.
• Metabolite & Residue Analysis: Serves as a reference standard in analytical laboratories for food safety testing and regulatory compliance monitoring.
• Research & Development: Utilized in microbiological and pharmacological studies to investigate antibacterial mechanisms and resistance.
• Intermediate Synthesis: Acts as a key chemical intermediate in the synthesis of more complex sulfonamide derivatives.
