This chemical is primarily used in organic synthesis as a building block for the creation of more complex molecules. It is particularly valuable in cross-coupling reactions, such as the Stille coupling, where it facilitates the formation of carbon-carbon bonds. This makes it useful in the production of pharmaceuticals, agrochemicals, and advanced materials. Additionally, it serves as a key intermediate in the synthesis of heterocyclic compounds, which are important in drug discovery and development. Its application in polymer chemistry also aids in the modification of polymer structures to achieve desired properties. Due to its reactivity and versatility, it is a valuable tool in research and industrial chemistry.
