Quality Control

Our S-3,3'-Bis[4-(2-Naphthalenyl)Phenyl]-1,1'-Binaphthalene]-2,2'-Diol is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and chiral purity (enantiomeric excess), to ensure it meets rigorous research and production standards. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting identity, assay, and impurity profiles.

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 light-sensitive nature and propensity to be easily oxidized, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from strong oxidizing agents.
