Solubility
Copper(I) iodide is soluble in ammonia, thiosulfate, sodium and potassium iodide solutions. Insoluble in water and dilute acids.

Applications

It is used as a catalyst in organic synthesis, cathode ray tube coating, cloud seeding, and as temperature indicator with HgI<sub>2</sub>. It catalyzes the conversion of aryl, heteroaryl, and vinyl bromides into the corresponding iodides, which are employed in coupling reactions such as Suzuki, Stille, Sonogashira, Heck and Ullmann reactions.

Notes

It is generally stable in air and is photosensitive.
