Quality Control

Our production of 2-(7-Bromo-9,9-Dioctyl-9H-Fluoren-2-Yl)-4,4,5,5-Tetramethyl-[1,3,2]Dioxaborolane adheres to stringent quality management protocols to ensure batch-to-batch consistency and high purity, essential for sensitive cross-coupling reactions. Each lot undergoes comprehensive analysis including HPLC for purity, NMR (1H, 13C, 11B) for structural confirmation, and GC-MS to monitor residual solvents. Certificates of Analysis (COA) detailing all specifications are provided and can be tailored to meet specific customer or regulatory requirements.

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 sealed under an inert atmosphere (argon or nitrogen) when not in use to prevent moisture absorption and degradation. Keep away from heat and incompatible materials.
