Quality Control

Our 8-Quinolinesulfonic Acid, Hydrate (6Ci) is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with key parameters including assay, water content, and impurity profiles. Our quality commitment ensures the material meets the high standards required for research and industrial synthesis.

Storage

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