Used as a catalyst and building block in organic synthesis, particularly in pharmaceutical and agrochemical industries. It facilitates reactions such as alkylations, acylations, and polymerizations due to its strong basicity and nucleophilic character. Commonly employed in the preparation of ionic liquids, which are used as green solvents in industrial processes. Also finds use in the synthesis of functional materials and as a ligand in coordination chemistry for metal-catalyzed reactions. Its role in drug development includes incorporation into bioactive molecules and antimicrobial agents.
