HPLC Method Separation of 1,3-Diaminopropane, 1,4-Diaminobutane (Putrescine) and 1,5-Diaminopentane (Cadaverine) on Primesep 200 Column Chromatogramm

Separation type: Liquid Chromatography Mixed-mode

1,3-Diaminopropane, or trimethylenediamine, is a key heterocycle building block and precursor of the chemotherapy antineoplastic agents Prioxantrone and Losoxantrone. 1,4-Diaminobutane, or Putrescine, is one of the main sources of the foul odor of rotting flesh, but has found use as a building block of Nylon 46. 1,5-Diaminopentane, or Cadaverine, is another source of the foul odor of rotting flesh and since its produced by the decarboxylation of lysine, can be used as a biomarker for lysine metabolic deficiencies.

These (putrid) diamines can be retained, analyzed, and separated on a Primesep 200 column using an isocratic analytical method with a simple mobile phase of water, Acetonitrile (MeCN), and an Ammonium formate (AmFm) ionic modifier. This analysis method can be detected with an Evaporative Light Scattering Detector (ELSD) or any other evaporative detection method (CAD, ESI-MS).
