FAQs
1. What is the solubility of this sodium phosphate monobasic dihydrate?
It is highly soluble in water (about 830 g/L at 20°C) and slightly soluble in ethanol, making it suitable for aqueous buffer preparations.
2. Can this be used for preparing phosphate-buffered saline (PBS)?
Yes, this HPLC-grade reagent is commonly used as a component in PBS formulations due to its high purity and consistent performance.
3. What is the difference between monobasic and dibasic sodium phosphate?
Monobasic sodium phosphate (NaH₂PO₄) has one replaceable hydrogen ion, while dibasic (Na₂HPO₄) has two, affecting their pH and buffering capacity.
4. How should this product be stored to maintain its quality?
Store in a tightly sealed container at room temperature, protected from moisture and direct sunlight to prevent degradation.
5. Is this product compatible with mass spectrometry applications?
Yes, its HPLC-grade purity makes it suitable for mass spectrometry, as it minimizes background noise and ion suppression.
