Potassium phosphate, dibasic, trihydrate

Potassium phosphate, dibasic, trihydrate is an inorganic salt with the chemical formula K₂HPO₄·3H₂O. It is a highly water-soluble compound used primarily as an electrolyte replenisher and buffering agent in pharmaceutical preparations and laboratory settings. In clinical practice (often as part of intravenous solutions), it serves to correct or prevent hypokalemia and hypophosphatemia by providing both potassium and phosphorus ions. The mechanism of action involves direct supplementation of these essential electrolytes to maintain normal cellular function and acid-base balance. It is classified as a small molecule mineral supplement.
