Quality Control

Our 8-Hydroxy-7-Nitroso-5-Quinolinesulfonic Acid is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for research and industrial synthesis. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting all critical quality parameters.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (typically 15-25°C). Keep away from incompatible materials such as strong oxidizing agents. Due to its light-sensitive nature, containers should be amber-colored or stored in light-resistant packaging.
