Tin(IV) iodide is used in the preparation of tin(IV) oxide and tin(II) oxide. It reacts with hydroiodic acid to get rare tin hexaiodide. It forms tetraiodobis triphenylphosphine tin complexes by reacting with triphenylphosphine, which finds application in toothpaste formulation. Further, it acts as analytical reagents and also used in organic synthesis.

COMPOUNDS and IODIDES.
It is recrystallised from anhydrous CHCl3, dry it under vacuum and store it in a vacuum desiccator. It sublimes at 180o.
