Ammonium phosphate monobasic is widely used as a fertilizer in agriculture due to its high solubility and ability to provide both nitrogen and phosphorus, essential nutrients for plant growth. It is particularly effective in promoting root development and enhancing crop yield. In the food industry, it serves as a leavening agent in baked goods, helping dough rise by releasing carbon dioxide when heated. Additionally, it is utilized in fire extinguishers as a flame retardant, where it helps suppress flames by forming a protective layer on combustible materials. In laboratories, it is employed as a buffer solution to maintain stable pH levels in various chemical and biological experiments. Its versatility makes it valuable across multiple industries.
