Quality Control

Our Tetrakis(Neopentolato)Diboron is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including NMR (¹H, ¹¹B, ¹³C), HPLC for purity assessment, and Karl Fischer titration for moisture content, to ensure it meets the high standards required for research and process chemistry. Certificates of Analysis (COA) with full traceability are provided with every shipment.

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). Due to its hygroscopic nature, the container must be kept tightly sealed under an inert atmosphere (argon or nitrogen) after opening to prevent moisture absorption and decomposition.
