If you are looking for optimized HPLC method to analyze Pentosan, Pentosan Polysulfate check our HPLC Applications library

For optimal results in HPLC analysis, it is recommended to measure absorbance at a wavelength that matches the absorption maximum of the compound(s) being analyzed. The UV spectrum shown can assist in selecting an appropriate wavelength for your analysis. Please note that certain mobile phases and buffers may block wavelengths below 230 nm, rendering absorbance measurement at these wavelengths ineffective. If detection below 230 nm is required, it is recommended to use acetonitrile and water as low UV-transparent mobile phases, with phosphoric acid and its salts, sulfuric acid, and TFA as buffers.
For some compounds, the UV-Vis Spectrum is affected by the pH of the mobile phase. The spectra presented here are measured with an acidic mobile phase that has a pH of 3 or lower.

Heparin and pentosan are highly-sulfated glucosaminoglucan, widely used in pharmaceutical industry. Both molecules carry a high negative density attributed to multiple sulfate groups. Due to a very polar and polymeric nature of these compounds, separating and quantifying them is a very difficult task. Heparin and its salt, along with pentosan, are separated on a Primesep N column in HILIC/anion-exclusion mode. Method can be used for quantitation of heparin and pentosan in biofluids and formulations. Elution is monitored by ELSD, CAD or LC/MS.
