General description
Lithium aluminum anhydride is effective as a selective reducing agent.[1]The anhydride may be prepared by reacting lithium hydride with aluminum chloride.[2] It is soluble in ether[3] and it can reduce carboxyl group to primary alcohol group with great ease.[2] Other organic compounds that can be reduced by lithium aluminum hydride are aldehydes, ketones, acid chlorides, acid anhydrides,[3] halides, quinones, nitrogen compounds.[4]
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Find details here.
Application
Lithium aluminum hydride (LAH) can be used as a promising material for hydrogen storage applications. Its properties include high gravimetric and volumetric hydrogen densities.[5][6][7]
Lithium aluminum hydride can be used to prepare undec-10-en-1-ol, a key intermediate for the preparation of polythioethers.[8]

Why should I use Product 323403, the LAH pellets, instead of a fine crystalline powder?
1 answer-
The pellets are recommended for safety reasons. Powdered lithium aluminum hydride can form potentially explosive dust-air mixtures. But use of the lithium aluminum hydride pellets, which can tolerate exposure to air for a short period of time, avoids the dusting associated with the powder. Please note that longer dissolving times, perhaps up to 90 minutes at room temperature, need to be taken into account when using the pellet form.
