Quality Control

Every batch of 2,7-Bis(4,4,5,5-Tetramethyl-1,3,2-Dioxaborolan-2-Yl)Naphthalene is produced and tested under strict quality management protocols to ensure high purity, batch-to-batch consistency, and reliable performance in sensitive applications like pharmaceutical synthesis. Our products undergo rigorous analytical testing, including NMR and HPLC, to confirm identity and purity. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place at 2-8°C or as specified on the label. This material is hygroscopic (moisture-sensitive) and easily oxidized; prolonged exposure to air and moisture must be avoided to maintain product integrity. Keep container tightly sealed when not in use.
