Used in the synthesis of pharmaceuticals and biologically active compounds, particularly in the development of imidazole-based drugs. It serves as a key intermediate in the preparation of antifungal, antiviral, and anticancer agents due to its ability to alkylate various nucleophiles. Commonly employed in medicinal chemistry for modifying peptides and nucleosides, enhancing their biological activity or stability. Also utilized in the production of ionic liquids and as a building block in heterocyclic chemistry for creating complex molecular architectures.
