HPLC Method for Separation of Acetaminophen and 4-Aminophenol on Primesep 100 Column
Separation type: Liquid Chromatography Mixed-mode
4-Aminophenol (also known as para-aminophenol or Rodinal) is a popular film developing compound and building block in organic chemistry reactions. Most notably, it is a key compound used in the production of acetaminophen (also known as paracetamol or Tylenol). 4-Aminophenol can be separated, retained, and analyzed on a Primesep 100 mixed-mode stationary phase column using an isocratic analytical method with a simple mobile phase of water, Acetonitrile (MeCN), and an sulfuric acid (H2SO4) or perchloric acid (HClO4) buffer. This analysis method can be detected in the UV regime at 220 nm.
