Used as a strong base and nucleophile in organic synthesis, particularly in condensation and deprotonation reactions. Commonly employed in the preparation of fine chemicals, pharmaceuticals, and asymmetric synthesis. Serves as a catalyst or reagent in esterification, transesterification, and aldol reactions. Also utilized in the production of lithium-containing materials and in some polymerization processes. Its solubility in organic solvents makes it suitable for reactions requiring anhydrous and basic conditions.
