KH?PO? - Buffer & Chromatography Applications

Potassium dihydrogen phosphate is widely used to prepare phosphate buffer systems in the pH 4.5-7.5 range for enzyme assays and HPLC mobile phases.

Its defined stoichiometry and high purity support reproducible ionic strength and retention times in ion?pair and aqueous HPLC methods.

In clinical and research labs it also serves as a calibration salt, conductivity standard component, and nutrient in microbiological media.

Compatible with many organic modifiers, it helps stabilize analytes that are sensitive to pH drift during long gradient runs.
