2-Fluoroiodobenzene is primarily used as a versatile intermediate in organic synthesis, particularly in the development of pharmaceuticals and agrochemicals. Its unique structure, featuring both fluorine and iodine atoms, makes it valuable for introducing fluorinated aromatic rings into complex molecules, which is crucial in drug design to enhance metabolic stability and bioavailability. Additionally, it serves as a key reagent in cross-coupling reactions, such as the Suzuki-Miyaura and Ullmann reactions, enabling the formation of carbon-carbon and carbon-heteroatom bonds. This compound is also employed in the synthesis of liquid crystals and advanced materials, where its electronic properties are leveraged for specific applications.
