CAS 865-34-9 Lithium Methoxide Solid
Overview
Lithium Methoxide (crystalline, CH₃OLi, CAS 865-34-9) is a white, highly hygroscopic alkoxide supplied as a strong base/nucleophile for demanding synthesis.Compared with solution grades, the crystalline form offers convenient weighing, storage, and reduced solvent load while maintaining high reactivity for transesterification, alkoxide formation, O-alkylation, condensations, and other base-catalyzed steps in pharmaceuticals, fine chemicals, and polymer chemistry.
Product Description
CAS 865-34-9 Lithium Methoxide Solid
Lithium methoxide is a versatile reagent widely applied in organic synthesis, biodiesel production, polymer modification, pharmaceuticals, and energy materials. As a strong base and efficient catalyst, it promotes ester exchange, condensation, and selective transformations, while also serving as a valuable lithium source for advanced materials such as lithium-ion batteries. Its high reactivity, catalytic efficiency, and unique lithium-ion effects make it an essential tool across both research and industrial applications.
