Quality Control

Our 4-[1-(3-Carboxy-4-Hydroxy-1-Naphthyl)-3-Oxo-1H,3H-Naphtho[1,8-Cd]Pyran-1-Yl]-1-Hydroxy-6-(Octadecyloxy)-2-Naphthoic Acid is produced under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods, to ensure it meets exacting research and industrial-grade specifications. A detailed Certificate of Analysis (COA) documenting batch-specific results is provided with each shipment 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 (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.
