Quality Control

Our 2,2'-[(1,2-Diphenyl-1,2-Ethenediyl)Di-4,1-Phenylene]Bis[4,4,5,5-Tetramethyl-1,3,2-Dioxaborolane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and NMR for structural confirmation, to ensure compliance with exacting R&D and process chemistry standards. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, the product should be stored under an inert atmosphere (argon or nitrogen) in a cool, dry place. Recommended long-term storage temperature is 2-8°C. Allow the sealed container to equilibrate to room temperature before opening to prevent moisture condensation.
