Sodium phosphate tribasic dodecahydrate (CAS 10101-89-0)

Sodium phosphate tribasic dodecahydrate (Na3PO4·12H2O), also known as trisodium phosphate dodecahydrate, is a highly water-soluble inorganic compound that exhibits both buffering and chelating properties. This compound is commonly used in various industrial applications where it serves as a cleaning agent, stain remover, and degreaser due to its ability to saponify fats and oils, effectively breaking them down. In the field of chemistry research, sodium phosphate tribasic dodecahydrate is particularly valued for its role in preparing buffer solutions. These buffer solutions are essential in biochemical and molecular biology experiments where maintaining a stable pH is crucial for the activity and stability of biomolecules such as enzymes and nucleic acids. Its buffering capacity makes it ideal for controlling the pH in reactions and processes that are sensitive to acidic or basic conditions. Additionally, its chelating properties are exploited in the sequestration of metal ions, preventing metal-catalyzed degradation processes in various analytical procedures. This chelation capability is also beneficial in water treatment processes, where it helps in softening water by removing calcium and magnesium ions. Through these diverse applications, sodium phosphate tribasic dodecahydrate plays a crucial role in both industrial processes and scientific research, proving its utility in enhancing product performance and ensuring the reliability of experimental outcomes.
