CAS 865-34-9: Lithium methoxide

Lithium methoxide, 10% in methanol

Lithium methoxide is used in sol-gel synthesis of lithium borophosphates. It is also useful for deprotonation reactions in organic synthesis. Further, it serves as a mild base in organic synthesis especially in transesterifications. This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Lithium methoxide, min. 95%

Lithium methoxide is a chemical compound that has been used in the synthesis of amides and hydroxyl compounds. It is an asymmetric synthesis catalyst that is used to form glycol ethers, which are widely used as solvents and additives. Lithium methoxide is formed in the reaction of lithium metal with methanol, glycerin, or ethylene oxide. The reaction mechanism for this process involves lithium metal reacting with water to form lithium hydroxide, followed by a nucleophilic attack on the carbonyl group of the molecule. This process produces a particle that can be seen under a microscope, so it is also known as "lithium soap." Lithium methoxide has been shown to be stable in organic media such as glycol ethers and fatty acids. It has also been shown to have electrochemical impedance spectroscopy properties that are similar to those of fatty acids.
