Used as a strong, non-nucleophilic base in organic synthesis, particularly in deprotonation reactions where high selectivity is required. It is effective in the formation of enolates from carbonyl compounds and facilitates aldol-type condensations without significant side reactions. Its bulky structure enhances steric control, making it valuable in asymmetric synthesis and pharmaceutical intermediates preparation. Also employed in polymerization catalyst systems and as a reagent in the synthesis of fine chemicals and agrochemicals.
