Quality Control

Our 3,3,3',3'-Tetramethyl-1,1'-Spirobiindan-5,5',6,6',7,7'-Hexol is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods (NMR, IR), to ensure it meets exacting R&D and production standards. Certificates of Analysis (COA) detailing batch-specific results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, the product should be stored in a cool, dry place, ideally at controlled room temperature (15-25°C). For long-term storage, consider using desiccants or storing under an inert atmosphere to maintain stability and purity.
