Quality Control

Our Benzo[B]Naphtho[2,3-D]Furan, 2-(4,4,5,5-Tetramethyl-1,3,2-Dioxaborolan-2-Yl)- is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and MS, to ensure high purity and structural integrity suitable for sensitive cross-coupling applications. Certificates of Analysis (COA) with detailed specifications are 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 place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container should be kept tightly sealed in a desiccated environment to prevent moisture absorption, which can compromise the reactivity of the boronic ester group. For long-term storage, consider storing under an inert atmosphere such as argon or nitrogen.
