Application

HPLC Labeling Reagent for Amines and Thiols

The compound 1 which is an HPLC fluorescence labeling reagent having a 2,1,3-benzoxadiazole skeleton, can easily react with amino and mercapto groups to form the corresponding derivatives. The derivatives are stable enough to reach the detector without any decomposition under reversed phase HPLC. An excellent chromatogram can be obtained by fluorescence detection at the excitation and emission wavelengths of 450 nm and 590 nm, respectively.

Application example:
[Amino acids]
0.5 mL of 20 mM labeling reagent in acetonitrile is put into an amber-glass vial. To this solution, add 0.5 mL of 0.1 M boric acid buffer solution (pH 9.3, containing 1mM EDTANa2) containing several nmol of an amino acid, and incubate at 50 ºC for 30 min. After cooling the reaction mixture with ice bath, use it as an HPLC sample.
For example, the detection limit (S/N=3) for proline is 0.11 pmol.
