Quality Control

Our 7,8-Quinolinediamine(9Ci) is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) detailing batch-specific results are available upon request. We adhere to cGMP principles where applicable to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture. Keep away from strong oxidizing agents.
