HPLC Method for Analysis of Ethyl Red

HPLC Method for Ethyl red on Newcrom R1 by SIELC Technologies

HPLC Method for Analysis of Ethyl red

High Performance Liquid Chromatography (HPLC) Method for Analysis of Ethyl red 

Ethyl red is a pH indicator with C₁₇H₁₉N₃O₂ as its molecular structure. When the pH transitions from acidic to neutral, Ethyl red turns from yellow to red, hence the name. Outside of experiments, it is occasionally used as a dye in textiles and foods.

Ethyl red can be retained and analyzed using the Newcrom R1 stationary phase column. The analysis utilizes an isocratic method with a simple mobile phase consisting of water and acetonitrile (MeCN) with a phosphoric acid buffer. Detection is performed using UV.
