Quality Control

Our 2-[4-[3,5-Bis[4-(4,4,5,5-Tetramethyl-1,3,2-Dioxaborolan-2-Yl)Phenyl]Phenyl]Phenyl]-4,4,5,5-Tetramethyl-1,3,2-Dioxaborolane is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including NMR (¹H, ¹³C, ¹¹B), HPLC, and GC analysis, to ensure identity, purity, and consistency. We provide a detailed Certificate of Analysis (COA) with every shipment, confirming compliance with customer specifications and internal quality standards. Our commitment to traceability and batch-to-batch reproducibility makes us a reliable partner for critical R&D and scale-up projects.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic (moisture-sensitive) nature, the container should be kept sealed under an inert atmosphere (argon or nitrogen) when not in use. Recommended long-term storage temperature is 2-8°C. Allow the container to reach room temperature before opening to prevent moisture condensation.
