Quality Control

Our 6-Quinolinecarboxylic Acid, 4,7-Dihydroxy-2-Methyl- (9Ci) is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods, to ensure it meets exacting R&D and process standards. Certificates of Analysis (COA) with detailed specifications are available for every shipment upon request.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature and propensity to be easily oxidized, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place. For long-term stability, storage at 2-8°C is advised.
