Used as a deicing agent for roads and runways, especially in areas where environmental concerns limit the use of chloride-based salts. It is effective at low temperatures and is less corrosive to metals, making it suitable for use in airports to prevent ice formation on aircraft surfaces and runways.

Commonly employed in the food industry as a buffering agent and preservative, helping to control acidity and extend shelf life in processed foods and condiments.

Serves as a source of potassium in pharmaceutical formulations and intravenous solutions, particularly in cases of potassium deficiency or metabolic acidosis. It also acts as a solubilizer in injectables and inhalers.

Utilized in organic synthesis as a mild base or catalyst, especially in reactions requiring a non-nucleophilic anion, and as a starting material in certain syntheses.

Applied in gas scrubbing systems to remove carbon dioxide and hydrogen sulfide from industrial gas streams due to its ability to form reversible complexes with acidic gases.

Used in some fire extinguishing agents, particularly for Class K fires involving cooking oils and fats, where it helps form a heat-resistant soapy layer that suppresses flames.

In laboratory settings, it is used for pH control in experiments, including chromatography processes, and as a moisture absorbent in environmental applications like ventilation and cooling systems.
