Sodium Phosphate, Monobasic

Sodium phosphate monobasic (or monosodium phosphate, MSP) is an inorganic compound, formula NaH₂PO₄, used widely as a buffer in biochemistry, molecular biology (like chromatography), as a laxative, in food/beverages, and to treat low phosphorus levels (hypophosphatemia); it's a white powder or crystal, soluble in water, and acts as an acid salt. It's the sodium salt of phosphoric acid, with a high buffering capacity to control pH in solutions.
