Description

Flomoxef is a broad-spectrum oxacephem antibiotic belonging to the β-lactam class, valued for its potent activity against a wide range of Gram-positive and Gram-negative bacteria. Its primary commercial value lies in its role as a key active pharmaceutical ingredient (API) and critical intermediate in the synthesis of advanced antibiotic formulations. This compound is essential for manufacturers in the pharmaceutical industry, particularly those developing injectable antibiotics for hospital use to combat resistant infections.

Application

• Active Pharmaceutical Ingredient (API): Primary use in the manufacture of finished antibiotic drugs, especially injectable formulations.
• Pharmaceutical Intermediate: Serves as a crucial building block in the synthesis of more complex antibiotic molecules and prodrugs.
• Research & Development: Used in microbiological and pharmacological research to study bacterial resistance mechanisms and develop new therapeutic agents.
• Reference Standard: Employed as a high-purity standard in quality control laboratories for HPLC, LC-MS, and other analytical methods.
• Veterinary Medicine: Potential application in developing antibacterial treatments for animal health.

Quality Control

Our Flomoxef is manufactured under strict quality management systems to ensure it meets the rigorous standards required for pharmaceutical applications. Each batch is tested against comprehensive specifications, including identity, purity, and impurity profiles, with methods aligned with ICH guidelines. A Certificate of Analysis (COA) documenting all test results is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a low-humidity environment to prevent degradation.
