Guanylurea phosphate is widely used in agriculture as a highly effective fertilizer. It provides a balanced supply of nitrogen and phosphorus, essential nutrients for plant growth, enhancing crop yield and quality. Its slow-release properties ensure a steady nutrient supply, reducing the risk of over-fertilization and environmental runoff. Additionally, it is utilized in the pharmaceutical industry as an intermediate in the synthesis of various drugs, particularly those targeting metabolic and cardiovascular conditions. Its stability and solubility make it a valuable component in formulations requiring precise nutrient or active ingredient delivery.
