Product Overview
Potassium dihydrogen phosphate AnalaR NORMAPUR® reagent (Ph. Eur) is a high-purity, crystalline powder designed for critical laboratory applications where precision and consistency are paramount. This reagent-grade compound meets the stringent standards of the European Pharmacopoeia (Ph. Eur), ensuring minimal impurities and reliable performance in analytical procedures. Its exceptional solubility in water makes it ideal for preparing buffer solutions, particularly in biochemical and molecular biology experiments where stable pH control is essential. The AnalaR NORMAPUR® designation guarantees a product that has undergone rigorous quality control, delivering batch-to-batch uniformity for reproducible results. With a well-defined molecular structure (KH₂PO₄), this reagent offers excellent thermal stability and compatibility with a wide range of laboratory protocols. The 250 g packaging provides an optimal balance between bulk efficiency and freshness preservation, while the airtight container protects against moisture absorption and contamination. This product represents the gold standard for potassium phosphate salts in research and quality control laboratories.
FAQs
1. What is the solubility of Potassium dihydrogen phosphate AnalaR?
This reagent exhibits high solubility in water, with approximately 220 g/L at 20°C, forming clear, colorless solutions suitable for buffer preparation.
2. How does this compare with standard laboratory-grade potassium phosphate?
The AnalaR NORMAPUR® grade offers significantly lower impurity levels (typically <0.001% heavy metals) compared to standard laboratory grades, with certified compliance to Ph. Eur standards.
3. What storage conditions are recommended for maintaining product integrity?
Store in a tightly sealed container at room temperature (15-25°C) in a dry environment, protected from direct sunlight and moisture to prevent caking or degradation.
4. Is this product compatible with HPLC applications?
While primarily used for buffer preparation, its high purity makes it suitable for HPLC mobile phase preparation when proper filtration (0.22 μm) is applied prior to use.
5. What documentation is provided with this reagent?
Each batch includes a Certificate of Analysis detailing purity levels, heavy metal content, pH of solution, and compliance with Ph. Eur specifications for full traceability.
