Used as a catalyst and solvent in organic synthesis, particularly in polymer chemistry and pharmaceutical manufacturing. Commonly employed in the production of epoxy resins where it acts as a curing agent, enhancing thermal and mechanical properties of the final product. Also utilized in the synthesis of ionic liquids, which have applications in green chemistry and electrochemical systems such as batteries and fuel cells. Plays a role as a ligand in coordination chemistry and in the preparation of pharmaceutical intermediates due to its strong nucleophilic and basic properties.
