Application
HPLC Labeling Reagent
The compound 1 is an HPLC fluorescence labeling reagent, which reacts with many kinds of nucleophilic groups under mild conditions. The reaction examples are shown in the table below.
These resulting compounds are stable, and can reach the detector without any decomposition under reversed phase HPLC, thus excellent chromatograms can be obtained by fluorescence detection.

Application examples:
10 µL of 25 mM labeling reagent 1 in dry benzene is mixed with 10 µL of 0.5 mM androsterone in dry benzene (containing 0.5 mM quinuclidine＊), and incubated at 60 °C for 30 min. The reaction solution is quenched with 980 µL of 50% acetonitrile solution containing 1% acetic acid, use it as the HPLC sample solution.
＊For primary alcohols, quinuclidine is not necessarily needed.
