General description

The polymorphism of 1-eicosanol has been studied by X-ray powder diffraction, differential scanning calorimetry (DSC), Raman scattering and IR spectroscopy.

Application

1-Eicosanol has been used:
  • in gradient HPLC-charged aerosol detection method for the detection of different lipids
  • as internal standard during determination of policosanol′s high molecular weight alcohols (policosanol′s fatty alcohols) in fish oil by GC
