Dipotassium phosphate (K2HPO4) (also dipotassium hydrogen orthophosphate; potassium phosphate dibasic) is a highly water-soluble salt which is often used as a fertilizer, food additive and buffering agent. It is a common source of phosphorus and potassium. A dipotassium phosphate solution is formed by the stoichiometric reaction of phosphoric acid with two equivalents of potassium hydroxide:H3PO4 + 2 KOH → K2HPO4 + 2 H2O.

Dipotassium phosphate uses as a food additive, also used in imitation dairy creamers, dry powder beverages, mineral supplements, and starter cultures. It is used in non-dairy creamers to prevent coagulation.
