SUZUKI REACTION MONITORING Using Compact Mass Spectrometry with TLC Interface

Dedicated to Science, Dedicated to You

This application note presents an online thin-layer chromatography (TLC)/CMS technique using the Advion expression compact mass spectrometer (CMS) and Plate ExpressTM interface to provide compound structural information without sample preparation after TLC separation. A Suzuki reaction for the synthesis of 4-aminobiphenyl will be demonstrated. The online TLC/CMS technique provides rapid and accurate determination of reaction mixture components without the need for off-line TLC sample preparation procedures.
