If you are looking for optimized HPLC method to analyze 1,3-Diaminopropane check our HPLC Applications library

For optimal results in HPLC analysis, it is recommended to measure absorbance at a wavelength that matches the absorption maximum of the compound(s) being analyzed. The UV spectrum shown can assist in selecting an appropriate wavelength for your analysis. Please note that certain mobile phases and buffers may block wavelengths below 230 nm, rendering absorbance measurement at these wavelengths ineffective. If detection below 230 nm is required, it is recommended to use acetonitrile and water as low UV-transparent mobile phases, with phosphoric acid and its salts, sulfuric acid, and TFA as buffers.
For some compounds, the UV-Vis Spectrum is affected by the pH of the mobile phase. The spectra presented here are measured with an acidic mobile phase that has a pH of 3 or lower.

HPLC Method for Analysis of 1,5-Diaminopentane (Cadaverine), 1,3-Diaminopropane, 1,4-Diaminobutane (Putrescine) on Primesep 200 by SIELC Technologies

Separation type: Liquid Chromatography Mixed-mode

1,3-Diaminopropane, or trimethylenediamine, is a diamine with the chemical formula C₃H₁₀N₂. It is the key heterocycle building block and precursor of the chemotherapy antineoplastic agents Prioxantrone and Losoxantrone. You can find detailed UV spectra of 1,3-Diaminopropane and information about its various lambda maxima by visiting the following link.

1,4-Diaminobutane, or Putrescine, is an organic compound with the chemical formula C₄H₁₂N₂. It is one of the main sources of the foul odor of rotting flesh. On the industrial scale, it is produced by the hydrogenation of succinonitrile as it has found use as a building block of Nylon 46. It has been proposed to be used as a biochemical marker for determination of how long a corpse has been decomposing.

1,5-Diaminopentane, or Cadaverine, is an organic compound with the chemical formula C₅H₁₄N₂. It is a 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. You can find detailed UV spectra of 1,5-Diaminobutane and information about its various lambda maxima by visiting the following link.

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).
