General description

Lithium aluminum anhydride is effective as a selective reducing agent.The anhydride may be prepared by reacting lithium hydride with aluminum chloride. It is soluble in ether and it can reduce carboxyl group to primary alcohol group with great ease. Other organic compounds that can be reduced by lithium aluminum hydride are aldehydes, ketones, acid chlorides, acid anhydrides, halides, quinones, nitrogen compounds.
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.
Lithium aluminum hydride can be used to prepare undec-10-en-1-ol, a key intermediate for the preparation of polythioethers.
