Quality Control

Our Cefpodoxime Proxetil 4,7-Seco-Dimer is produced under strict quality management systems. The product undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the stringent requirements for pharmaceutical intermediates. Certificates of Analysis (COA) are available upon request, detailing batch-specific results for all critical quality attributes.

Storage

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