Quality Control

Our S-3,3'-Dibromo-1,1'-Binaphthyl-2,2'-Diyl Hydrogenphosphate is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure high chemical and chiral purity, meeting the exacting standards required for advanced synthetic applications. Certificates of Analysis (COA) detailing purity, enantiomeric excess, and impurity profiles are provided to guarantee batch-to-batch consistency and traceability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) when opening the container for use to prevent degradation.
