Quality Control

Our 4,4,5,5-Tetramethyl-2-(4-{2-[4-(Tetramethyl-1,3,2-Dioxaborolan-2-Yl)Phenyl]Ethyl}Phenyl)-1,3,2-Dioxaborolane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and elemental analysis, to ensure high purity and batch-to-batch consistency suitable for sensitive cross-coupling applications. Certificates of Analysis (COA) detailing all specifications are available upon request.

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 (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
