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 a secondary amine and thiol. The resultant derivative is stable enough to reach the detector without any decomposition under general reversed phase HPLC. An excellent chromatogram can be obtained by fluorescence detection analysis at the excitation and emission wavelengths of 46 nm and 535 nm, respectively. Application example:[Alkylamines] 1)To 25~5 μL of a methanol solution containing an amine (1~2 μg), 4~8 eq. excess amount of .5% labeling reagent 1 / methanol solution is added. After adding 5~1 μL of .1 M NaHCO3, incubate at 55 ºC for 1~5 h. After cooling the reaction mixture to room temperature, use it as an HPLC sample.[Others]TLC and HPLC of N-methylcarbamates, N,N-dimethylcarbamates in agrichemicals2,3) Hydrolyze the carbamates to label the amine derivatives.TLC of amphetamines in urine4,5), HPLC of prolines (precolumn derivatization method)6)TCI Products Pamphlet
