Product Description
When your research demands uncompromising precision, every reagent counts. This di-Potassium Hydrogen OrthoPhosphate (K₂HPO₄) from CDH is meticulously purified to meet the stringent requirements of HPLC and spectroscopy applications. Whether you’re preparing buffers for chromatographic separations or calibrating instruments for spectral analysis, this analytical-grade phosphate salt delivers consistent, reliable performance.
The HPLC-grade certification ensures minimal impurities that could interfere with sensitive detectors or skew retention times. For spectroscopy, its high optical clarity guarantees accurate absorbance readings without background noise. Researchers in biochemistry, molecular biology, and environmental testing rely on this reagent for its batch-to-batch consistency—critical when reproducibility is non-negotiable.
Beyond its technical specifications, this potassium phosphate salt offers practical advantages in daily lab work. Its fine, free-flowing powder dissolves rapidly in aqueous solutions, saving valuable time during buffer preparation. The stable pH buffering capacity (pKa ~7.2) makes it ideal for maintaining physiological conditions in cell culture media or enzymatic assays. Unlike lower-grade alternatives, this product undergoes rigorous quality control to prevent lot variability that could compromise experimental outcomes.
For students setting up their first chromatography experiments or seasoned researchers optimizing protocols, having a dependable source of high-purity chemicals is essential. Eqipped understands these needs, which is why we stock only verified, lab-tested reagents like this CDH-certified di-Potassium Hydrogen OrthoPhosphate.

FAQs
What’s the difference between this HPLC grade and regular lab grade potassium phosphate?
The HPLC grade undergoes additional purification to remove trace metals and organic impurities that could interfere with chromatographic separations or spectroscopic measurements. It’s certified to have lower levels of UV-absorbing contaminants and particulate matter.
Can I use this for preparing cell culture media?
Yes, this grade is suitable for cell culture applications when properly sterilized. The high purity helps maintain consistent osmolality and pH in culture media. Always filter-sterilize before adding to cell cultures.
What’s the typical shelf life of this product?
When stored properly in its original container at room temperature, this product maintains its specifications for at least 2 years. Always check for any signs of moisture absorption before use.
Do I need to adjust pH when preparing buffers with this?
This is the dibasic form (K₂HPO₄), so when used alone it creates alkaline solutions. For neutral pH buffers, it’s typically combined with monobasic potassium phosphate (KH₂PO₄) in appropriate ratios.
Is this product suitable for food or pharmaceutical applications?
While it’s high-purity grade, this specific product is intended for laboratory use only. For food or pharmaceutical applications, you would need a grade that meets additional regulatory requirements like USP or FCC standards.
