Application

Dansylhydrazine can exhibit fluorescence, which can be used for the following:
  • monitoring air pollution by detection of the hydrazones formed by acid-catalyzed derivatization of the carbonyl compounds
  • detection of the separated glycoproteins via sodium dodecyl sulfate polyacrylamide gel electrophoresis(SDS-PAGE)
