Used primarily in organic synthesis, this compound acts as a key intermediate in the formation of carbon-carbon bonds. It is particularly valuable in Stille coupling reactions, where it facilitates the cross-coupling of organotin compounds with organic halides or pseudohalides to produce complex organic molecules. This process is widely applied in the pharmaceutical industry for the development of drug candidates, as well as in materials science for the synthesis of advanced polymers and electronic materials. Additionally, its role in creating heterocyclic compounds makes it useful in the production of agrochemicals and dyes.
