Quality Control

Our 2,2'-(5-Cyclohexyl-1,3-Phenylene)Bis(4,4,5,5-Tetramethyl-1,3,2-Dioxaborolane) is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including NMR, HPLC, and GC analysis, to ensure high chemical purity and consistency suitable for sensitive cross-coupling applications. Certificates of Analysis (COA) with detailed chromatographic data are provided to guarantee traceability and compliance with your research or production specifications.

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