Quality Control

Our 6-Quinolinecarboxylicacid,1,2-Dihydro-3-Methyl-2-Oxo-(9Ci) 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 stringent requirements of research and process development. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key specifications such as assay, impurity profile, and physical characteristics.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. For long-term storage, consider using desiccants.
