Potassium phosphate dibasic trihydrate, often abbreviated as K2HPO4-3H2O, is a chemical compound that contains potassium (K+), hydrogen (H+), phosphate (PO43-) ions, and three water molecules (tri meaning three and hydrate referring to water molecules). This compound is a hydrated form of potassium phosphate dibasic, indicating that it contains water molecules within its crystal structure.
Buffering Agent: Like its anhydrous counterpart, potassium phosphate dibasic trihydrate is commonly used as a buffering agent in various biochemical and molecular biology applications. It helps maintain a stable pH in solutions, particularly in the physiological range.
Fertilizer: It can be used as a source of potassium and phosphorus in agricultural applications to promote plant growth and development.
Laboratory Reagent: It is used as a reagent in chemical and biochemical experiments and analyses.
Biological Applications: In biological research, potassium phosphate dibasic trihydrate may be used in the preparation of cell culture media and as a component of phosphate-buffered saline (PBS) solutions for cell and tissue culture.
