Used as a dust suppressant on roads and construction sites due to its hygroscopic nature, which helps retain moisture and reduce airborne particles. Commonly applied in winter road maintenance as a de-icing agent because it lowers the freezing point of water and works effectively at low temperatures. Employed in agriculture as a source of magnesium for plant nutrition, especially in magnesium-deficient soils. Utilized in the production of tofu as a coagulant to curdle soy milk. Found in pharmaceuticals and dietary supplements for magnesium deficiency treatment. Serves as a precursor in the synthesis of other magnesium compounds and in industrial processes such as textile and paper manufacturing.
