Quality Control

Our 1,2-Bis(4,4,5,5-Tetramethyl-[1,3,2]Dioxabororan-2-Yl)Benzene is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including NMR, HPLC, and elemental analysis, to ensure high purity and batch-to-batch consistency suitable for demanding synthetic applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic nature, the container should be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and degradation. Recommended long-term storage temperature is 2-8°C.
