🧪 1. Product Description

Dipotassium Phosphate (DKP), also known as Potassium Phosphate Dibasic, is an inorganic potassium salt of phosphoric acid with the chemical formula K₂HPO₄. It appears as a white, free-flowing crystalline powder or granules and is highly soluble in water.

DKP is widely used as a source of potassium (K) and phosphorus (P) in agriculture, food processing, fermentation, pharmaceuticals, and industrial applications. Due to its excellent solubility and buffering capacity, it is particularly valued in fertilizer formulations, pH regulation systems, and nutrient media.
