Application
HPLC Labeling Reagent for Carbonyl Compounds
The compound 1 is an HPLC labeling reagent, which has a hydroxylamino moiety, can easily react with a carbonyl group to form the corresponding oxime. The resultant oxime 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.
Application examples:
[Aldehydes] 1)
1~5 mg of a sample, 4 mL of methanol, 2 drops of triethylamine, and 40 mg of the labeling reagent 1 are mixed. Close the cap of the reaction vessel and incubate the mixture at 65 °C for 1 h. After cooling to room temperature, use it as the HPLC sample solution. If it is necessary to remove the unreacted labeling reagent and triethylamine, evaporate the solvent at a low temperature under a nitrogen atmosphere. Dissolve the residue in 2~3 mL of ether and wash with diluted HCl and water.
