Description générale

The pentafluorophenylpropyl stationary phase of Ascentis Express F5 provides a stable reversed phase packing with electron-deficient phenyl rings due to the presence of electronegative fluorines.In addition to forming pi-pi and mildly steric interactions, F5 phases also retain compounds by polar interactions. Ascentis Express F5 can be used for basic, acidic, or neutral compounds with alternate selectivity from C18.

Application

  • Liquid chromatographic determination of lumacaftor in the presence of ivacaftor and identification of five novel degradation products using high-performance liquid chromatography ion trap time-of-flight mass spectrometry.: This study employs the Ascentis® Express F5, 2.7 μm HPLC Column to enhance the resolution and sensitivity in the analysis of lumacaftor and ivacaftor, critical medications for treating cystic fibrosis. The method provides significant insights into the stability and degradation pathways of these drugs, facilitating improved drug formulation and storage conditions (Ozcan et al., 2023).
  • Stability-indicating LC-MS/MS and LC-DAD methods for robust determination of tasimelteon and high resolution mass spectrometric identification of a novel degradation product.: Utilizing the Ascentis® Express F5, 2.7 μm HPLC Column, this research develops advanced analytical techniques for tasimelteon, a treatment for non-24-hour sleep-wake disorder. The methods ensure accurate quantification and stability assessment, crucial for clinical efficacy and patient safety (Ozcan et al., 2020).

Research shows that immunoassay techniques are not the best choice for the estimation of vitamin D in human blood samples. The main reasons are that some immunoassays are not able to distinguish between 25-OHD3 and 25-OHD2 vitamin D metabolites. Furthermore
