Quality Control

Our Diethyl(1-Ethynylcyclohexyloxy)Borane is manufactured under strict quality systems. Each batch undergoes rigorous analytical testing, including NMR and GC/HPLC, to ensure high purity and consistency for synthetic applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) in a cool, dry, and well-ventilated place. Recommended storage temperature is 2-8°C. Due to its moisture-sensitive and easily oxidized nature, the container should be purged with inert gas after each opening to maintain product integrity.
