Quality Control

Our 1,1'-Spirobiindane-7,7'-Diol is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity determination by HPLC, to ensure it meets the high standards required for research and development applications. A comprehensive Certificate of Analysis (COA) detailing purity, enantiomeric excess, and other critical parameters is provided with every shipment.

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 nature, the container must be kept tightly sealed to minimize exposure to atmospheric moisture. For long-term storage, consider using desiccants or an inert atmosphere.
