Quality Control

Our 9,9-Di-n-Octylfluorene-2-Boronic Acid Pinacol Ester is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity for sensitive coupling reactions. All products undergo rigorous analytical testing, including HPLC, NMR, and GC-MS, to confirm identity and purity. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each 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 place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) when opening the container for use to prevent degradation.
