Product Overview
Sodium phosphate monobasic, anhydrous (99% purity) is a high-quality reagent designed for analytical applications where precision and consistency are critical. This fine, white crystalline powder offers excellent solubility in water, forming clear solutions that maintain stable pH levels—making it indispensable for buffering systems in biochemical and molecular biology protocols. Its anhydrous nature ensures minimal moisture content, reducing variability in experimental results. The reagent’s high purity (99%) minimizes impurities that could interfere with sensitive assays or spectrophotometric measurements. Commonly used as a component in phosphate-buffered saline (PBS) formulations, this compound provides reliable ionic strength and pH control for cell culture, protein purification, and diagnostic testing. Its stable chemical structure ensures long shelf life when stored under recommended conditions, while its non-hygroscopic properties simplify handling and weighing. Whether used in titration, chromatography, or enzymatic reactions, this analytical-grade sodium phosphate monobasic delivers reproducible performance, meeting the stringent requirements of research laboratories, quality control testing, and educational demonstrations.
FAQs
1. What is the solubility of anhydrous sodium phosphate monobasic in water?
It dissolves readily in water, with a solubility of approximately 85 g/100 mL at 20°C, forming a slightly acidic solution.
2. Can this product be used for preparing phosphate-buffered saline (PBS)?
Yes, it is a key component in PBS formulations due to its buffering capacity and compatibility with biological systems.
3. How does this differ from the dihydrate form of sodium phosphate monobasic?
The anhydrous form lacks water molecules, offering higher purity by weight and eliminating variability from hydration levels.
4. What is the typical shelf life of this reagent when stored properly?
When stored in a tightly sealed container at room temperature, it remains stable for at least 3–5 years.
5. Is this suitable for HPLC or other high-sensitivity applications?
While primarily designed for general analytical use, its 99% purity makes it compatible with many HPLC applications requiring low impurity levels.
