Quality Control

Our 7-Chloro-4-Hydroxy-8-Methylquinoline-3-Carboxylic Acid is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for research and synthesis applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area 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. Keep away from incompatible materials such as strong acids and organic solvents.
