Used as a deicing agent for roads and runways, especially in airports where chloride-free alternatives are required to prevent corrosion of aircraft and infrastructure. Also employed in food processing as a buffering agent and preservative, helping to control acidity and extend shelf life. In the pharmaceutical industry, it serves as an electrolyte replenisher in intravenous fluids to treat low potassium levels. Additionally, it functions as a catalyst or reactant in organic synthesis and is used in some fire extinguisher formulations due to its ability to suppress flames. Its hygroscopic nature makes it useful in gas drying and purification processes.
