Quality Control

Our Cibenzoline is manufactured under strict quality management systems. Every batch undergoes comprehensive analytical testing to ensure it meets stringent purity and identity specifications, suitable for pharmaceutical applications. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming compliance with agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to minimize exposure to atmospheric moisture. For long-term storage, consider the use of desiccants.
