Quality Control

Every batch of Dipyrido[2,3-B:3,2-I]Anthyridine, Radical Ion(1-) is produced and handled under controlled conditions to ensure consistency and purity for research applications. We employ advanced analytical techniques, including HPLC, NMR, and EPR spectroscopy, to verify chemical identity, radical purity, and the absence of significant impurities. A comprehensive Certificate of Analysis (COA) detailing batch-specific results is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Due to its sensitivity to light and oxygen, long-term storage is recommended under an inert atmosphere (argon or nitrogen) at temperatures between 2°C and 8°C. The container should be kept in a cool, dry, and well-ventilated place away from incompatible materials.
