Quality Control

Our Cephalosporin C Zinc Salt is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for pharmaceutical intermediates. Certificates of Analysis (COA) are provided with every shipment, detailing batch-specific results.

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 nature, the container must be kept tightly sealed in a low-humidity environment to prevent moisture absorption and degradation.
