Potassium Phosphate丨CAS 7778-53-2

Potassium phosphate丨7778-53-2, refers to a group of inorganic salts composed of potassium cations (K⁺) and phosphate anions (PO₄³⁻). The most common forms are monopotassium phosphate (KH₂PO₄), dipotassium phosphate (K₂HPO₄), and tripotassium phosphate (K₃PO₄). These compounds are widely used in food, pharmaceuticals, agriculture, and industrial applications due to their buffering, nutritional, and chemical properties.
