Di Ammonium Hydrogen Phosphate – 500 gram Packs

Di Ammonium Hydrogen Phosphate, also known as Diammonium Hydrogen Phosphate or Diammonium Phosphate, is an inorganic salt of phosphoric acid with the chemical formula (NH₄)₂HPO₄. It consists of two ammonium ions and one hydrogen phosphate ion and forms a white crystalline solid that dissolves readily in water. Its aqueous solutions generally exhibit mildly alkaline characteristics, making it relevant to investigations involving phosphate chemistry, acid–base equilibria, and solution preparation. This compound is used in analytical chemistry, inorganic chemistry practicals, microbiological media preparation, and selected biochemical research procedures where ammonium and phosphate ions are required. It can also serve as a component in suitable phosphate buffer systems when the formulation and experimental conditions permit. Lab Wale offers Di Ammonium Hydrogen Phosphate in 500 gram packs for appropriate educational, analytical, and research laboratory applications, subject to the required grade and procedure-specific specifications.
