Application
HPLC Labeling Reagent for Amines

The compound 1 is an HPLC labeling reagent for optical purity determination, which has a glyco-moiety and an isothiocyano group, and easily reacts with an amino group to form the corresponding thiourea. The resultant thiourea is stable enough to reach the detector without any decomposition under reversed phase HPLC. An excellent chromatogram can be obtained by measuring at 254 nm, an absorption wavelength that is generally used for UV detection. Furthermore, 1 reacts with a racemic amine to generate diastereomers, which can be efficiently separated by reversed phase HPLC.

Application examples:
[Amino acids] 1)
5 mg of an amino acid is dissolved in 50% (V/V) aqueous acetonitrile containing 0.4% (W/V) triethylamine in order to give a final volume of 10 mL. To 50 µL of this solution 50 µL of 0.2% (W/V) labeling reagent 1 in acetonitrile are added. The resulting mixture is shaken at room temperature for 30 min and used as an HPLC sample.
