Potassium Chloride is a metal halide composed of potassium and chloride. Potassium maintains intracellular tonicity, is required for nerve conduction, cardiac, skeletal and smooth muscle contraction, production of energy, the synthesis of nucleic acids, maintenance of blood pressure and normal renal function. This agent has potential antihypertensive effects and when taken as a nutritional supplement may prevent hypokalemia.Potassium chloride appears as white colorless cubic crystals. Strong saline taste. (NTP, 1992)

It is mainly used in the inorganic industry as a basic raw material for manufacturing various potassium salts and alkalis, such as potassium hydroxide, potassium sulfate, potassium nitrate, potassium chlorate, potassium dichromate, etc.In the pharmaceutical industry, it is used as a diuretic and a drug for preventing and treating hypokalemia.In the dye industry, it is used in the production of G-salt, reactive dyes, etc.In agriculture, it is used as a potassium fertilizer.
