Key Applications
This HPLC-grade sodium phosphate dibasic is commonly used in:
- Buffer preparation for biochemical assays
- HPLC and other chromatographic techniques
- Molecular biology protocols, including DNA/RNA extraction
- Pharmaceutical research and formulation
- Cell culture media and microbiological studies
Why This Grade Matters
Not all sodium phosphate dibasic is created equal. The HPLC grade ensures that the chemical is free from contaminants that could interfere with sensitive analytical instruments. This makes it a preferred choice for researchers who need consistent, reproducible results. Unlike technical or industrial grades, this variant undergoes rigorous testing to confirm its suitability for high-precision applications.
For students and educators, using HPLC-grade chemicals in experiments helps reinforce the importance of quality reagents in scientific accuracy. It’s a small but crucial detail that can make a significant difference in experimental outcomes.
Handling and Storage
To maintain the integrity of this chemical, store it in a cool, dry place away from direct sunlight. Ensure the container is tightly sealed to prevent moisture absorption, as this product is anhydrous. Always use appropriate personal protective equipment (PPE), such as gloves and goggles, when handling chemicals in the lab.

Safety Considerations
While sodium phosphate dibasic is generally safe when handled properly, it’s important to follow standard laboratory safety protocols. Avoid inhalation or direct contact with skin and eyes. In case of accidental exposure, rinse thoroughly with water and seek medical attention if irritation persists.
FAQs
What is the difference between sodium phosphate dibasic and monobasic?
Sodium phosphate dibasic (Na₂HPO₄) has two sodium ions and one hydrogen ion, making it slightly basic. Monobasic sodium phosphate (NaH₂PO₄) has one sodium ion and two hydrogen ions, making it more acidic. The dibasic form is often used for buffering solutions in the pH range of 8-12.
Can this product be used for food or pharmaceutical applications?
This HPLC-grade sodium phosphate dibasic is intended for laboratory use only. For food or pharmaceutical applications, you would need a grade specifically certified for those purposes, such as USP or food-grade variants.
How do I prepare a phosphate buffer using this chemical?
To prepare a phosphate buffer, mix sodium phosphate dibasic with sodium phosphate monobasic in the appropriate ratio to achieve your desired pH. A common starting point is a 0.1M solution of each, adjusted with HCl or NaOH as needed.
What is the shelf life of anhydrous sodium phosphate dibasic?
When stored properly in a sealed container, this product has a long shelf life, typically 2-3 years. However, always check for signs of moisture absorption or clumping before use.
