Quality Control

Our trans-4,4,5,5-Tetramethyl-2-Oct-1-Enyl-1,3,2-Dioxaborolane is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including NMR (¹H, ¹³C, ¹¹B), HPLC, and GC analysis, to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment to support your quality assurance and regulatory compliance 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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (argon or nitrogen) after opening to prevent degradation. Keep away from incompatible materials such as strong oxidizers.
