Physico-Chemical Measurements

  • EPSA: SFC based measurement estimating the compounds’ polar surface area and its tendency of forming internal hydrogen bonds

  • Solubility: Measure peak area ratios relative to the peak in DMSO or methanol solution

  • Stability: Samples in aqueous solutions reanalyzed after 24 hours and compare to the original purity

  • LogD: Calculated based on retention time using a calibration curve generated by a shallow water/acetonitrile gradient

  • Glutathione Reactivity Measurement

  • Solubility and stability in simulated gastric solutions

  • Rilas can customize the measurements for any biologically relevant buffers customers require
