Used as a strong base in organic synthesis, particularly in deprotonation reactions and condensation processes. Commonly employed in the production of fine chemicals and pharmaceuticals where anhydrous basic conditions are required. Serves as a catalyst or reagent in esterification, transesterification, and Michael addition reactions. Also utilized in the preparation of lithium-containing materials and in some polymerization processes. Due to its reactivity with moisture and air, it is handled under inert atmosphere conditions.
