Quality Control

Our (4R,4'R)-2,2'-Diethyl(4,4'-Bi-1,3,2-Dioxaborolane)-5,5'-Dione is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity and chemical assay determination, to ensure it meets the high standards required for research and production. Certificates of Analysis (COA) detailing purity, enantiomeric excess, and impurity profiles are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at 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.
