Food grade KCl is used in food processing as a sodium-free substitute for table salt for persons concerned about the health effects of sodium, fertilizer production, medicine and other scientific applications. Suitable for use in all food industries and pharmaceutical industry.

Solutions of KCl are common standards, for calibration of the electrical conductivity of ionic solutions, since KCl solutions are stable, allowing for reproducible measurements. In aqueous solution, it is essentially fully ionized into solvated K+ and Cl– ions.
