HPLC Labeling Reagent for Carboxylic Acids
The compound 1 an HPLC fluorescence labeling reagent, which has a 2,1,3-benzoxadiazole skeleton and a hydrazino group, easily reacts with a carboxyl group to form the corresponding carbohydrazide in the presence of a condensing agent. The resultant carbohydrazide is stable for at least one week at 4 °C. The carbohydrazide derivatives can be analyzed by reversed phase HPLC, and an excellent chromatogram can be obtained by fluorescence detection at the excitation and emission wavelengths of 475 nm and 530 nm, respectively. [The detection limit = 2~4 fmol (S/N = 3)]
Application example:
Add 50 µL of carboxylic acid / DMF solution, 50 µL of 1.0 M EDC aqueous solution, 50 µL of 20% pyridine aqueous solution and 20 mM HPLC labeling reagent 1 / DMF solution to a vessel, and incubate the mixture at room temperature for 2 h. Dilute this reactant mixture 10x with the mobile phase solution, and use 1 µL of this diluted solution as an HPLC sample solution.
