Quality Control

Our 4,4,5,5-Tetramethyl-2-[1,1':3',1''-Terphenyl]-3-Yl-1,3,2-Dioxaborolane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR and HPLC, to ensure high purity and consistency suitable for sensitive cross-coupling applications. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and decomposition.
