Used as a dust suppressant on unpaved roads, magnesium chloride helps bind fine particles and reduce airborne dust. It is also widely applied for de-icing roads and sidewalks in winter due to its ability to lower the freezing point of water, even at low temperatures. In agriculture, it serves as a magnesium source in fertilizers, supporting chlorophyll production in plants. The compound is used in the production of tofu as a coagulant to curdle soy milk. In medicine, it is administered as a supplement to treat magnesium deficiency. Additionally, magnesium chloride is employed in industrial processes such as textile manufacturing, paper production, and as a catalyst support in certain chemical reactions.
