Versatile Applications Across IndustriesDipotassium Phosphate finds wide utility as a buffer, emulsifier, and nutrient additive in food, pharmaceuticals, agriculture, water treatment, and laboratory research. Its high solubility and stability make it suitable for both large-scale industrial processes and precise laboratory formulations, with specific grades available for food, industrial, and laboratory usage.
Physical and Chemical PropertiesThis odorless, white crystalline powder dissolves quickly in water, producing an alkaline solution with a pH of 8.69.6 at a 5% concentration. It is hygroscopic, stable at ambient conditions, and decomposes before boiling. The product is easily stored with a shelf life of 24 months, provided containers are kept tightly sealed and in a dry, cool environment.
FAQs of DI POTASSIUM PHOSPHATE:
Q: How is Dipotassium Phosphate commonly used in different industries?
A: Dipotassium Phosphate serves primarily as a buffering agent, emulsifier, and nutrient source. It is added to processed foods, used in pharmaceutical formulations, incorporated as a fertilizer component, and employed as a laboratory reagent for its reliable chemical properties.
Q: What are the benefits of using Dipotassium Phosphate in food and pharmaceuticals?
