HPLC Method for Benzocaine on Primesep 200 by SIELC Technologies
High Performance Liquid Chromatography (HPLC) Method for Analysis of Benzocaine
Benzocaine is a local anesthetic with the chemical formula C9H11NO2. It is primarily used to treat pain in the mouth, threat, and ears. On occasion it is also used on sunburns and hemorrhoids. It is also commonly used as a ingredient ibn other medications. You can find detailed UV spectra of Benzocaine and information about its various lambda maxima by visiting the following link.
Benzocaine can be retained and analyzed using the Primesep 200 stationary phase column. The analysis utilizes an isocratic method with a simple mobile phase consisting of water and acetonitrile (MeCN) with a sulfuric acid as a buffer. Detection is performed using UV.
