Quality Control

Our B-[4-(4-Dibenzothienyl)Phenyl]-Boronic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and elemental analysis, to ensure high chemical purity and consistent performance in sensitive coupling reactions. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request 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.
