Quality Control

Our Diethyl[(E)-1-Ethyl-2-Methyl-1-Butenyl]Borane is manufactured under controlled conditions to ensure high purity and batch-to-batch consistency. Each lot undergoes rigorous analytical testing, including NMR spectroscopy and chromatographic methods, to confirm identity and purity. Certificates of Analysis (COA) detailing all specifications are 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, containers must be kept sealed and handled under inert conditions to maintain product integrity.
