Quality Control

Our (R)-2,2'-Binaphthyl-17-Crown-5 is produced under strict quality management protocols to ensure high chiral purity and chemical integrity. Each batch is characterized by advanced analytical techniques, including chiral HPLC, to confirm enantiomeric excess (ee) and overall purity. Certificates of Analysis (COA) detailing specific results for identity, assay, and chiral purity are available upon request.

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 nature, the container should be kept in a desiccated environment to prevent moisture absorption, which could affect performance. Handle and store under an inert atmosphere for long-term stability.
