Main Uses
Agricultural Field: As a highly efficient water-soluble phosphorus and potassium compound fertilizer, containing approximately 52% P₂O₅ and approximately 52% K₂O. 34% Can be applied through foliar spraying, drip irrigation, seed soaking, seed dressing, and root dipping.Effects include: promoting photosynthesis, root development, flower bud differentiation, fruit enlargement and coloring, and enhancing stress resistance (cold resistance, drought resistance, disease and pest resistance, etc.).
Food Industry: As a food additive (INS No. 340(i)), it is used to regulate acidity, buffer stability, and provide yeast nutrition. It is commonly used in baking, dairy products, and beverages to improve texture and extend shelf life. Food-grade potassium dihydrogen phosphate must meet national standard GB 25560—2010, with a purity ≥98%.
Research and Industry: Used to prepare standard buffer solutions and maintain pH stability in biochemical experimental systems.Its crystal (KDP) has nonlinear optical and electro-optic properties and is used to manufacture high-end optical devices such as laser modulators and frequency converters. It is also used in pharmaceuticals, antibiotic production, and feed additives.To purchase, search for “potassium dihydrogen phosphate”. For potassium dihydrogen phosphate manufacturers, look for keywords like “purity of over 98%”!
