The main use of potassium chloride is in the manufacture of fertilizers. It finds use in medicine as an electrolyte replenisher, and to treat hypokalemia with its pharmaceutical preparation, a condition in which the level of potassium will be low in blood. Further it finds use as a flux agent in welding and metal casting. It is useful in water softener units, certain de-icing products and calibration of the radiation monitoring equipment. It finds use as a scotophor in dark-trace CRTs.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
