Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antifungal and anticancer agents. Its structure allows for easy functionalization, making it valuable in medicinal chemistry for building complex heterocyclic systems. Also employed in the preparation of ligands for metal-catalyzed reactions, enhancing catalytic efficiency in organic transformations. Additionally, it finds use in materials science for designing ionic liquids and functional polymers due to its ability to form stable salts and coordinate with metal ions.
