Quality Control

Our 7,7'-(4,4'-Biphenylylenebis(Carbonylimino))Bis(1-Ethylquinolinium) Di-p-Toluenesulfonate is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via NMR and IR spectroscopy, to ensure it meets exacting research and industrial grade specifications. Comprehensive Certificates of Analysis (COA) detailing all test results are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a low-humidity environment to prevent degradation. For long-term storage, consider the use of desiccants.
