3-aminopropanol is a degradation product of panthenol (active ingredient in many creams). it present in low concentrations, so sample of the cream would have a large amount of cream. so what is the best method to determine it quantitatively?
Probably titration in inert solvent with two indicators and three standards. Other method NMR might be used. Also liquid chromatography if the crème dissolves in solvent.
HPLC would be a preferable method for detection of 3-aminopropanol present in low concentrations. Furthermore Spectrofluorimetric method could also be applied for the same. Please find the references.
