Analysis Method
MDEB purity calculated by GC. Concentration of THF solution calculated by boron titration
Storage & Shipping
Shelf Life
Four years in unopened, original packaging. Based upon like compounds.
Storage / Stability
Neat methoxydiethylborane is a spontaneously combustible liquid. The solution (<80 wt% MDEB) in THF, however, is non-pyrophoric. Exposure to air will oxidize MDEB solutions to other borate materials. MDEB also reacts readily with atmospheric moisture upon exposure to air resulting in a decrease in purity.
