Application
HPLC Labeling Reagent for Carboxylic Acids

The compound 1 is an HPLC fluorescence labeling reagent, which has a 2,1,3-benzoxadiazole skeleton and a piperazino group, easily reacts with a carboxyl group at room temperature to form the corresponding amide in the presence of a condensation reagent. An excellent chromatogram can be obtained by fluorescence detection at the excitation and emission wavelengths of 440 nm and 569 nm, respectively. Since their excitation and fluorescence wavelengths are at longer wavelengths, detection has less interference by contaminants. A highly sensitive analysis can be done by peroxyoxalate chemiluminescence detection1).

Application examples:
[Fatty acids] 2)
0.2 mL of 140 mM DEPC or 70 mM 2,2’-dipyridyl disulfide-Ph3P / DMF solution containing a fatty acid (10 µM) is added to 0.2 mL of the labeling reagent 1 / DMF or acetonitrile solution (10 mM). Incubate at room temperature for 6 h, then use it as an HPLC sample.
For example, the detection limit (S/N = 3) for saturated fatty acids (from C13 to C24) is from 3.2 to 4.7 fmol.
