Description:
Potassium Dihydrogen Orthophosphate (Anhydrous), also known as Monopotassium Phosphate (MKP) or Potassium Phosphate Monobasic, is a high-purity, white crystalline powder with the chemical formula KH₂PO₄ and a molecular weight of 136.09 g/mol. It is odourless, water-soluble, and slightly hygroscopic, possessing a mildly acidic pH of around 4.2–4.7 in aqueous solution. The compound remains stable under normal temperature and pressure but decomposes upon heating above 250 °C, releasing phosphorus oxides.
Specifications:
Typical specifications include a minimum purity of 98%, water-insoluble matter below 0.1%, and loss on drying less than 0.5%. The pH of a 1% solution is between 4.2 and 4.7, and heavy metal impurities such as lead, iron, and arsenic are maintained at very low levels to ensure safety and quality.
Uses and Applications:
Potassium Dihydrogen Orthophosphate is widely used as a fertilizer in agriculture due to its high phosphorus and potassium content, essential for plant growth and flowering. In the food industry, it serves as an emulsifier, acidity regulator, and nutrient additive (E340). It is also commonly used in laboratories as a buffering agent for chemical and biological research, and in pharmaceuticals as a mineral source. Additionally, it finds application in fire extinguishers, optical materials, and fermentation processes.
Storage:
Store the product in a cool, dry, and well-ventilated area, away from heat, moisture, and incompatible substances such as strong acids or bases. Containers should be kept tightly sealed to prevent clumping or degradation. Under proper storage conditions, the material maintains stability for up to 2–3 years.
Hazardous Information:
Potassium Dihydrogen Orthophosphate is generally considered non-hazardous. It does not burn or support combustion but may cause mild irritation to the eyes, skin, or respiratory system if mishandled. Prolonged exposure to dust should be avoided. It is incompatible with strong acids, bases, and oxidising agents.
Safety Measures:
When handling, use protective gloves, goggles, and a dust mask to minimise exposure. Avoid inhaling dust and wash your hands thoroughly after handling. In case of eye or skin contact, rinse with plenty of water. For inhalation, move the affected person to fresh air. Spilled material should be carefully swept up to avoid dust generation, then disposed of in accordance with local regulations. The compound is non-flammable, but standard firefighting methods such as water spray, foam, or dry chemical extinguishers can be used in case of nearby fires.
