Used as a reagent in organic synthesis, particularly for the introduction of tributylstannyl groups into molecules. It is valuable in cross-coupling reactions, such as Stille coupling, which is widely applied in the formation of carbon-carbon bonds in complex organic compounds. Additionally, it serves as a precursor in the preparation of organotin compounds, which are utilized in various catalytic processes and material science applications. Its trifluoroacetate component can also enhance reactivity in certain transformations, making it useful in specialized synthetic pathways.
