Used primarily as a building block in organic synthesis, especially in the pharmaceutical industry. It serves as a reagent for introducing the 2,4-difluorophenyl group into more complex molecules. Its silicon-containing group facilitates cross-coupling reactions, such as Hiyama coupling, enabling the formation of carbon-carbon bonds under mild conditions. This makes it valuable in the development of active pharmaceutical ingredients (APIs) where fluorinated aromatic rings are needed to enhance metabolic stability and bioavailability. Also employed in the synthesis of agrochemicals and functional materials due to the unique electronic properties imparted by the fluorine atoms.
