Quality Control

Our 8-Quinolinesulfonic Acid, 5,7-Dichloro- is produced under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure high purity and consistency. Certificates of Analysis (COA) detailing specifications such as assay, identity, and impurity profiles are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture. Keep away from strong acids and organic solvents.
