Diammonium Phosphate (DAP) is a water-soluble ammonium phosphate salt with the chemical formula (NH₄)₂HPO₄. It serves as an important source of nitrogen (18%) and phosphorus (46%), making it widely useful in agriculture as a high-efficiency NP fertilizer to promote plant growth. Beyond farming, DAP is used as a yeast nutrient in winemaking/brewing, a fire retardant in industrial applications, and a corrosion inhibitor in water treatment systems. It also finds roles in animal feed supplements, pyrotechnics, and laboratory reagents. With its alkaline pH (~8.0) and solubility, DAP is versatile but requires careful handling due to ammonia release when heated.
