Used in organic synthesis as a building block for complex molecules, particularly in the development of pharmaceuticals and agrochemicals. It serves as a key intermediate in the creation of heterocyclic compounds, which are essential in drug discovery. Its iodine atom allows for further functionalization through cross-coupling reactions, enabling the construction of diverse chemical structures. Additionally, it is employed in materials science for the synthesis of organic electronic materials, such as light-emitting diodes (LEDs) and organic photovoltaics, due to its aromatic and heterocyclic properties.
