What is Potassium Phosphate Monobasic?

Potassium Phosphate Monobasic (KH₂PO₄), also known as Potassium Monophosphate, is a white crystalline inorganic compound (CAS No. 7778-77-0) used across food, agriculture, pharmaceutical, and laboratory sectors. It serves as a buffering agent, nutrient source, and pH stabilizer. Its high-purity EMPARTA® ACS grade is ideal for analytical use. Comprising potassium, hydrogen, and phosphate ions, it ensures precision and consistency in formulations requiring stable pH and mineral content. 

Key Chemical Properties of Potassium Monophosphate

Potassium dihydrogen orthophosphate monobasic is valued for its high solubility, stability, and buffering ability. Key properties include: 

  • pH Range: Acts as an acidic buffer, stabilizing pH between 4.5–5.5—crucial for precise biochemical processes. 
  • Solubility: Highly soluble in water, insoluble in alcohol—ideal for water-based systems. 
  • Thermal Stability: Maintains structure across varying temperatures, suitable for heat-treated formulations. 
  • Combustion: Non-combustible and safe under standard conditions. 
  • Controlled Release: Compatible with gradual nutrient or chemical release systems. 

These features make it a dependable, safe choice across industries. 

Molecular Formula and Composition

Understanding the molecular composition of Potassium Phosphate Monobasic helps in appreciating its behaviour and utility in different applications. 

  • Chemical Formula: KH₂PO₄ 
  • Molar Mass: 136.09 g/mol 
  • Composition: Comprises one potassium ion (K⁺), two hydrogen ions (H⁺), and a single phosphate ion (PO₄³⁻). 

The combination of potassium and phosphate ions is essential for plant nutrition and biological systems.  

Physical Characteristics – Appearance & Handling

How is Potassium Phosphate Monobasic Manufactured?

Potassium Monophosphate (KH₂PO₄) is produced through a controlled reaction between phosphoric acid and potassium hydroxide or potassium carbonate. 

Step-by-Step Process: 

  1. Neutralization: Phosphoric acid is neutralized with potassium hydroxide or carbonate under controlled conditions to form KH₂PO₄. 
  2. Filtration: The mixture is filtered to remove impurities. 
  3. Concentration: Water is evaporated to concentrate the solution. 
  4. Crystallization: Cooling induces crystal formation. 
  5. Drying & Packaging: Crystals are dried and packed under GMP-compliant conditions. 

Industrial Applications of Potassium Dihydrogen Orthophosphate

Due to its versatile nature, Potassium Dihydrogen Orthophosphate (KH₂PO₄) is extensively used across a wide range of industries: 

Food Industry: 

  • Used as a food additive (E340) for acidity regulation. 
  •  Serves as a mineral supplement in energy drinks, powders, and processed foods. 
  •  Helps maintain texture and stability in baked goods and dairy alternatives. 

Pharmaceuticals: 

  • Used as an electrolyte in IV fluids and oral rehydration salts (ORS). 
  •  Acts as a buffer in various pharmaceutical formulations. 
  •  Key ingredient in mineral supplements for potassium and phosphorus intake. 

Agriculture & Hydroponics: 

  • Used as a key source of phosphorus and potassium in NPK fertilizers. 
  • Promotes root development, flowering, and fruiting in plants. 
  • Ideal for hydroponic farming systems where water-soluble nutrients are essential. 

Chemical & Laboratory Use: 

  • Acts as a pH buffer in analytical chemistry and lab experiments. 
  • Used in preparing phosphate buffer solutions for cell cultures and biochemical assays. 

Water Treatment: 

  • Acts as a corrosion inhibitor by forming protective layers on metal surfaces. 
  • Prevents scale buildup in heating and cooling water systems.
