[Products Name]           Potassium iodide

 
[Molecular Formula]      KI

[CAS No.]                        7681-11-0        

[Applications]

The major uses of KI include nutritional supplement in animal feeds, a precursor to AgI,
and as a component in disinfectants. Potassium iodide is also added to hair chemicals,
and sometimes table salt in small quantities to make it "iodized." KI is also used as a fluorescence quenching agent in biomedical research because of collisional quenching by
its iodide ion.

A saturated solution of potassium iodide, abbreviated SSKI, is also used as treatment for sporotrichosis, a fungal infection. Since potassium iodide is highly soluble in water,
SSKI contains 1 gram KI per milliliter (mL) of solution. This is less than 100% by weight, because SSKI is significantly more dense than pure water.

Saturated solutions of potassium iodide can also be an emergency treatment for hyperthyroidism (so-called thyroid storm), as high amounts of iodide temporarily
supress secretion of thyroxine from the thyroid gland.
