Used as a strong, non-nucleophilic base in organic synthesis, particularly for deprotonation reactions where a less reactive base is required. It is effective in the preparation of sensitive intermediates, such as in the synthesis of pharmaceuticals and fine chemicals. The base is also employed in polymerization processes, especially for ring-opening polymerization of cyclic esters and carbonates, leading to the production of biodegradable polymers. Its steric bulk helps in minimizing side reactions, making it a valuable tool in complex organic transformations. Additionally, it is utilized in the development of advanced materials, including catalysts and specialty polymers, due to its stability and reactivity under various conditions.
