Quality Control

Our (9,9-Dimethyl-9H-Fluoren-3-Yl)Boronic Acid is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity suitable for demanding synthetic applications. Each lot undergoes comprehensive analytical testing, including HPLC, NMR (1H, 13C, 11B), and mass spectrometry, to confirm identity, purity, and the absence of critical impurities. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting all relevant specifications.

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 (argon or nitrogen) to prevent moisture absorption and decomposition. Keep away from incompatible materials.
