High Performance Liquid Chromatography (HPLC) Method for Analysis of 4-Amino-2-nitrophenol
4-Amino-2-nitrophenol is a hydrocarbon with the molecular formula C6H6N2O3 . It is a red-purple powder that is typically used in as an oxidation base in hair dye. California considers this compound a carcinogen.
4-Amino-2-nitrophenol can be retained and analyzed using the Primesep 100 stationary phase column. The analysis utilizes an isocratic method with a simple mobile phase consisting of water and acetonitrile (MeCN) with a sulfuric acid buffer. Detection is performed using UV.
