Description of key information

Additional information

Diisobutylaluminium hydride is highly reactive both towards oxygen (air) and water. It is exclusively marketed in liquid state and shipped under UN transport class 4.2 (substances liable to spontaneous combustion / pyrophoric liquids) or at least under class 4.3 (substances which in contact with water emit flammable gases).
Diisobutylaluminium hydride is an organometallic colourless clear pyrophoric liquid. The melting point is below - 20°C. This pyrophoric substance degrades before boiling. The density of diisobutylaluminium hydride is 0.798 g/cm³. The vapour pressure is 13.3 Pa at 90°C. The substance is water reactive so partition coefficient, watersolubility and surface tension are waived. Since diisobutylaluminium hydride is allready classified as pyrophoric and water reactive, flash point, autoflammability, flammability and oxidising properties are waived.
Diisobutylaluminium hydride is non explosive.
