Description

Cefapirin Sodium CAS NO 24356-60-3 is a semi-synthetic, first-generation cephalosporin antibiotic in its sodium salt form, offering enhanced stability and solubility for pharmaceutical formulation. This compound is critical for combating bacterial infections, particularly those caused by Gram-positive organisms, due to its mechanism of action involving inhibition of bacterial cell wall synthesis. It is primarily required by pharmaceutical manufacturers and research institutions engaged in the development and production of injectable antibiotic preparations and veterinary medicines.

Application

• Pharmaceutical Active Ingredient (API): Core component in the manufacture of sterile injectable antibiotic formulations for human use.
• Veterinary Pharmaceuticals: Used in the production of intramammary infusions and other treatments for bacterial infections in livestock, particularly mastitis in dairy cattle.
• Research & Development: Serves as a reference standard and key intermediate in microbiological research and the development of new antibacterial agents.
• Hospital Compounding: Utilized in pharmacy compounding for preparing specific dosage forms where commercial products are unavailable.

Quality Control

Our Cefapirin Sodium is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets high-purity standards suitable for pharmaceutical applications. A Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to guarantee traceability and compliance with relevant guidelines.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption, which can affect stability and potency.
