Disodium phosphate 

Disodium phosphate is commonly used as a food additive, buffer and laboratory reagent. Disodium phosphate has unique chemical properties that make it an important ingredient in the manufacture of fertilizers, detergents and water treatment products. Additionally, it is used in various medical applications such as osmotic laxatives and electrolyte replacement solutions.

Disodium phosphate is also known as Na₂HPO₄ to adjust pH of liquid. Disodium phosphate can be used as an excipient, such as buffer, chelating agent. Pharmaceutical excipients, or pharmaceutical auxiliaries, refer to other chemical substances used in the pharmaceutical process other than pharmaceutical ingredients. Pharmaceutical excipients generally refer to inactive ingredients in pharmaceutical preparations, which can improve the stability, solubility and processability of pharmaceutical preparations. Pharmaceutical excipients also affect the absorption, distribution, metabolism, and elimination (ADME) processes of co-administered drugs^[1][2].
