Quality Control

Our (R)-1,1'-Binaphthyl-2,2'-Disulfonimide is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high chemical purity. Each lot is characterized using advanced analytical techniques including HPLC, NMR, and chiral analysis to confirm identity, purity, and enantiomeric excess. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to support your quality assurance and regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled 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. For long-term storage, consider using desiccants.
