Description

Sulfamerazine Sodium CAS NO 127-58-2 is the sodium salt form of the sulfonamide antibiotic sulfamerazine, offering enhanced water solubility for formulation. This compound is a critical intermediate and active pharmaceutical ingredient (API) in the synthesis of veterinary and human antibacterial medications. It is primarily required by pharmaceutical manufacturers, veterinary drug producers, and research institutions developing antimicrobial therapies.

Application

• Pharmaceutical API: Core active ingredient in the manufacture of antibacterial formulations.
• Veterinary Medicine: Used in the production of treatments for bacterial infections in livestock and companion animals.
• Research & Development: Serves as a standard or intermediate in microbiological and pharmacological research.
• Intermediate Synthesis: Key building block for the chemical synthesis of more complex sulfonamide derivatives.
• Reference Standard: Utilized as a high-purity calibrant in analytical quality control laboratories.

Quality Control

Our Sulfamerazine Sodium is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets high-purity standards, including identification, assay, and impurity profile checks. Certificates of Analysis (COA) detailing the results are available upon request to support your regulatory and quality assurance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
