Used as a precursor in the synthesis of organotin compounds, which serve as catalysts in polymerization reactions and in the production of polyurethanes. Employed in research for the development of semiconductor materials due to its optical and electronic properties. Acts as a reagent in organic chemistry for iodination reactions and in the preparation of other tin-based compounds. Also explored in the fabrication of perovskite solar cells as a source of tin in the perovskite layer, offering a potential alternative to lead-based materials.
