Quality Control

Our Cefivitril is manufactured under strict quality management systems to meet the exacting standards of the pharmaceutical industry. Each batch undergoes comprehensive analytical testing, including HPLC for purity and assay, identification by spectroscopic methods, and stringent control of related substances and residual solvents. A Certificate of Analysis (COA) documenting full compliance with agreed specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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.
