If you are looking for optimized HPLC method to analyze Cytidine Triphosphate 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.

Nucleotides are important biological molecules which serve as subunits of nucleic acids. They are composed of a five-carbon sugar, a nitrogenous base, and at least one phosphate group. Nucleotides cannot be retained by reverse-phase chromatography without an ion-pairing reagent due to their highly polar nature. Primesep SB is capable of retaining and separating nine nucleotides. Primesep SB is a reverse-phase column with strong embedded basic ion-pairing groups.

Cytidine phosphates are nucleotides. Nucleotides contain a nucleobase, five-carbon sugar and one or three phosphate groups. All three cytidines are very polar and cannot be retained by reversed-phase chromatography without a ion-pairing reagent. Mixed-mode Primesep SB column easily allows to retain and separate mono-, di-, and tri-phospates by anion-exchange mechanism. Other nucleotides can be separated as well by this approach. Nucleotides in biofluids can be analyzed directly on this column without any significant sample preparation. Most of the proteins from biological fluids will be repelled from the surface of silica gel. Method is compatible with UV, ELSD, CAD and LC/MS.
