Product Overview
Sodium phosphate monobasic dihydrate LR is a high-quality laboratory reagent designed for precise applications in research and analytical settings. This crystalline powder, with the chemical formula NaH₂PO₄·2H₂O, is widely recognized for its role in buffer preparation, where it helps maintain stable pH levels in solutions. The LR (Laboratory Reagent) grade ensures minimal impurities, making it suitable for sensitive biochemical assays and experiments requiring consistent results. Its solubility in water allows for easy integration into various protocols, while its stability under standard lab conditions ensures long-term reliability. Whether used in molecular biology, biochemistry, or general chemistry, this compound provides the accuracy needed for reproducible outcomes. The dihydrate form offers enhanced handling convenience, reducing the risk of hygroscopicity compared to anhydrous alternatives. As a critical component in many lab workflows, it supports a broad range of applications without compromising on purity or performance.
FAQs
1. What is the solubility of sodium phosphate monobasic dihydrate in water?
Sodium phosphate monobasic dihydrate is highly soluble in water, typically dissolving at a rate of approximately 85 g/100 mL at 20°C, forming a clear, colorless solution.
2. Can this compound be used for preparing phosphate-buffered saline (PBS)?h4>
Yes, sodium phosphate monobasic dihydrate is a key ingredient in PBS formulations, where it works alongside disodium phosphate to achieve the desired pH and osmotic balance.
3. How should this product be stored to maintain its stability?
Store the compound in a tightly sealed container at room temperature, away from moisture and direct sunlight, to prevent degradation or clumping over time.
4. Is this LR grade suitable for cell culture applications?
While LR grade is generally pure, cell culture applications often require higher grades like AR or molecular biology grade to avoid potential contaminants that could affect cell viability.
5. What alternatives exist if this specific form is unavailable?
Alternatives include anhydrous sodium phosphate monobasic or dibasic sodium phosphate, though adjustments to concentration and pH may be necessary due to differences in water content and dissociation.
