Disodium Hydrogen Phosphate is produced through the neutralization of phosphoric acid with sodium hydroxide or sodium carbonate. The process involves controlled crystallization and drying to achieve the desired grade and purity.
The compound acts as a dibasic salt of phosphoric acid, enabling it to buffer solutions at a mildly alkaline pH. Its ability to bind with metal ions enhances its functionality in sequestration and stabilization applications.
