Quality Control

Our 2,2'-Oxybis[5,5-Dimethyl-1,3,2-Dioxaborinane] is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR, HPLC, and Karl Fischer titration, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with every shipment to support your quality assurance and regulatory needs.

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 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.
