Ammonium phosphate monobasic is widely used in agriculture as a highly effective fertilizer, providing essential nutrients like nitrogen and phosphorus to promote plant growth and improve crop yields. It is particularly beneficial in acidic soils, as it helps neutralize pH levels while supplying vital nutrients. In the food industry, it serves as a leavening agent in baked goods, aiding in the rising process and improving texture. Additionally, it is utilized in fire extinguishers as a flame retardant, where it helps suppress fires by releasing ammonia and forming a protective layer. In water treatment, it acts as a corrosion inhibitor, preventing scale formation and protecting metal surfaces in boilers and pipelines. Its versatility also extends to laboratory applications, where it is used as a buffering agent to maintain stable pH levels in various chemical processes.
