Quality Control

Our 1,1'-Bis(4-Methoxyphenyl)-[4,4'-Bipyridine]-1,1'-Diium Chloride is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC, NMR, and elemental analysis, to ensure high purity and batch-to-batch consistency. A Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment 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 nature, the container should be kept sealed under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent moisture absorption and degradation.
