Used as a deicing agent for roads and runways, especially where environmental concerns limit the use of chloride-based salts. It is effective at low temperatures and is less corrosive to metals and less harmful to vegetation and concrete. Commonly employed in the food industry as a preservative and acidity regulator, particularly in processed meats and cheeses, helping to control microbial growth and maintain flavor stability. Serves as a buffering agent in pharmaceutical formulations, ensuring stable pH in injectable medications and other sensitive preparations. Utilized in organic synthesis as a source of acetate ions, particularly in reactions requiring a non-nucleophilic base or mild alkaline conditions. Found in some fire extinguishing agents, where it helps suppress fires in cooking oils and fats by promoting saponification and forming a heat-resistant layer.
