Quality Control

Our 4-Quinolinecarboxylicacid,5-Hydroxy-6-Methyl-(9Ci) is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and NMR/IR for structural confirmation, to ensure it meets the high standards required for research and development. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee traceability and consistency for our global B2B clients.

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.
