Products Description of Potassium Chloride CAS#7447-40-7
Industrial-grade potassium chloride can achieve a purity of over 99%. It appears as a white, crystalline, fine granular powder; it is odorless and has a salty taste.
Potassium chloride has a melting point of approximately 770°C and a boiling point of about 1,420°C. Its vapor pressure at 25°C is negligible, and its relative density at 20°C is 1.98.
Potassium chloride is highly soluble in water and also soluble in glycerol. It is slightly soluble in ethanol but insoluble in ether and acetone. While the compound is chemically stable under normal conditions, it is incompatible with strong oxidizing agents.

Product Application of Potassium Chloride CAS#7447-40-7
Potassium chloride (KCl) is widely used in pharmaceutical preparations and serves as a food additive and chemical reagent. It can also be used as a substitute for table salt (sodium chloride) to help reduce sodium intake.
Molten potassium chloride is used in the electrolytic production of metallic potassium. Additionally, KCl occurs naturally in seawater brine and can be extracted from the mineral carnallite.
