2,4-Dibromo-1-iodobenzene is primarily used as an intermediate in organic synthesis, particularly in the production of complex aromatic compounds. It serves as a key building block in the development of pharmaceuticals, where it is utilized in the synthesis of active pharmaceutical ingredients (APIs). Additionally, this compound is employed in the creation of agrochemicals, contributing to the formulation of pesticides and herbicides. Its halogenated structure makes it a valuable reagent in cross-coupling reactions, such as Suzuki and Sonogashira couplings, which are essential in the synthesis of fine chemicals and advanced materials. In material science, it is used to develop organic electronic materials, including semiconductors and liquid crystals, due to its ability to modify electronic properties.
