| Questions and Answers (Q&A) | Back Directory | [Description]
Monosodium phosphate (MSP) is an inorganic compound of the elements sodium and phosphate counterion, which is often found in dental products, such as toothpastes and mouthwash related to its property of restoring lost enamel and preventing disease of the teeth and gums. It also finds application in medical use as a stimulant laxative before some operations and medical procedures. Besides, monosodium phosphate is also employed in food additive, like animal feed and evaporated milk, in which it serves as a thickening agent and emulsifier and provides the phosphorous supplement in the diet. It is also a common industrial chemical and chemical reagent used for detecting magnesium ions and adjusting the PH value.

| [Uses]
Sodium dihydrogen phosphate is used in industries such as boiler water treatment, electroplating, leather making, dyeing, pharmaceuticals, and food processing. | [Definition]
ChEBI: Sodium dihydrogenphosphate is a sodium phosphate. | [Synthesis]
Sodium dihydrogen phosphate is synthesized by the reaction of sodium chloride with orthophosphoric acid, or from the reaction of sodium chloride with orthophosphoric acid in the presence of an organic solvent or using an organic amine[1]. Sodium dihydrogen phosphate (NaH₂PO₄) is prepared via controlled neutralization of phosphoric acid with alkali metal bases or alkali metal hydroxides under continuous stirring, maintaining a temperature range of 40-70 °C[2]. |
