The compound 1 easily reacts with an amino group to form the corresponding 2,4-dinitrophenylamine derivative. The resultant derivative is stable and can 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. Application examples:[Amines]A sample (free amine) 1 mg, chloroform 1 mL, and labeling regent 1 (1 eq. excess amount of the sample) are mixed, and incubated at 6 ºC for 1 h. After cooling to room temperature, use it as an HPLC sample. 1 is also used for derivatization of amino acids.1,2)[Others]Aminoglycosides3)TCI Products Pamphlet
