Quality Control

Our 1,1'-Dimethyl-2,2'-Biquinolinium Bistetrafluoroborate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and elemental analysis, to ensure high purity and chemical identity. Certificates of Analysis (COA) detailing all specifications are provided with every shipment. We adhere to relevant industry standards and can support compliance documentation for research and industrial applications.

Storage

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