Ammonium Phosphate Dibasic DI Ammonium Hydrogen Orthophosphate

Ammonium Phosphate Dibasic, also known as Di-Ammonium Hydrogen Orthophosphate (DAP), is a highly water-soluble inorganic salt with the chemical formula (NH₄)₂HPO₄. It appears as a white crystalline powder or granular solid and is widely used in fertilizers, laboratory reagents, food processing, and industrial applications.

This compound serves as an important source of nitrogen and phosphorus, making it one of the most commonly used phosphate fertilizers. In aqueous solution, it produces a mildly alkaline pH, which makes it useful as a buffering agent in chemical and biological systems.

Ammonium phosphate dibasic is stable under normal storage conditions, but upon heating, it may decompose to release ammonia and phosphoric acid derivatives. It is non-combustible and compatible with most neutral materials, though it should be kept away from strong acids and oxidizing agents
