Product Overview
Potassium phosphate dibasic trihydrate (K₂HPO₄·3H₂O) is a high-purity, analytical-grade chemical designed for precise laboratory applications. With a minimum assay of 99%, this crystalline powder ensures consistent performance in pH buffering, biochemical assays, and reagent formulation. Its trihydrate form guarantees stability and solubility in aqueous solutions, making it a reliable choice for experiments requiring accurate phosphate ion concentrations. The compound’s low impurity profile minimizes interference in sensitive analytical procedures, while its standardized particle size distribution enhances dissolution rates. Ideal for use in molecular biology, biochemistry, and general lab protocols, this reagent adheres to strict quality control measures to meet the demands of research and educational environments. Store in a cool, dry place to maintain its integrity and extend shelf life.
FAQs
1. What is the solubility of this dibasic potassium phosphate?
It is highly soluble in water (167 g/L at 20°C) and forms a clear, colorless solution.
2. Can this be used for cell culture media preparation?
Yes, its high purity and low endotoxin levels make it suitable for cell culture applications.
3. How does this differ from anhydrous dibasic potassium phosphate?
The trihydrate form contains three water molecules, offering better solubility and handling in humid conditions.
4. What is the shelf life under proper storage conditions?
When stored in a sealed container at room temperature, it remains stable for 3–5 years.
5. Is this compatible with strong acids or bases?
It reacts with strong acids to form phosphoric acid and with bases to form potassium salts.
