Disodium Phenyl Phosphate Hydrate is widely used in biochemical research as a substrate for studying enzyme activity, particularly for phosphatases and kinases. It plays a crucial role in understanding cellular signaling pathways and metabolic processes. In industrial applications, it serves as a buffering agent in various formulations, helping to maintain pH stability in products like detergents and cleaning agents. Additionally, it is utilized in the synthesis of organic compounds, acting as an intermediate in the production of pharmaceuticals and agrochemicals. Its ability to release phosphate ions makes it valuable in water treatment processes, where it aids in controlling scale formation and corrosion.
