N,N-Bis(2-hydroxyethyl)-p-phenylenediamine (often abbreviated as N,N-Bis(2-hydroxyethyl)-PPD) is a chemical compound that is a derivative of p-phenylenediamine (PPD), a common ingredient in hair dyes.
The N,N-Bis(2-hydroxyethyl)-p-phenylenediamine be retained and analyzed using a Primesep 100 mixed-mode stationary phase column. The analysis employs an isocratic method with a simple mobile phase comprising water, acetonitrile (MeCN), and sulfuric acid as a buffer. This method allows for detection using UV at 210 nm
