Molecular Formula: K₃PO₄
Molecular Weight: 212.27 g/mol
Anhydrous Potassium Phosphate is a highly pure, water-soluble inorganic salt widely used as a buffering agent, pH regulator, and nutrient source in food processing, pharmaceuticals, agriculture, and industrial formulations.
As a potassium-based phosphate without water of crystallization, it offers higher active content, better stability, and longer shelf life compared to hydrated forms.
High Purity & Stability
Anhydrous form ensures consistent performance and longer storage life.
Excellent Solubility
Rapidly dissolves in water, suitable for liquid formulations.
Strong Buffering Capacity
Maintains stable pH in a wide range of applications.
Potassium Source
Provides essential potassium nutrient in fertilizers and food systems.
Low Moisture Content
Ideal for moisture-sensitive formulations.

Anhydrous potassium phosphate contains no water molecules, offering higher purity and stability, while hydrated forms contain bound water and may have lower active content.
Yes, food-grade anhydrous potassium phosphate can be used in food applications if it complies with relevant regulatory standards.
It mainly acts as a buffer, stabilizer, and emulsifier, helping control pH and improve product consistency.
Yes, it is an excellent source of potassium (K) and phosphorus (P), widely used in liquid and specialty fertilizers.
It should be stored in a dry and sealed environment to prevent moisture absorption and caking.
Generally compatible with many compounds, but compatibility testing is recommended for specific formulations.
