Used as a highly efficient arylating agent in organic synthesis, particularly for transferring aryl groups under mild conditions. It is effective in metal-catalyzed and metal-free reactions, enabling the formation of carbon-carbon and carbon-heteroatom bonds. Commonly applied in the synthesis of complex molecules, including pharmaceuticals and functional materials, due to its stability and high electrophilicity. Also utilized in radiofluorination reactions for positron emission tomography (PET) tracer development, where it facilitates the introduction of fluorine-18 into aromatic systems.
