3'-Methoxyphenacyl Bromide [for HPLC Labeling]

The compound 1 is an HPLC labeling reagent, which has a bromoacetyl group and easily reacts with a carboxyl group to form the corresponding ester in the presence of a base. The resultant ester 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:
[Fatty acids] ^{1~ 3)}
Dissolve 4 mg of a sample in 1 mL of N,N-dimethylformamide (DMF), and add the labeling reagent 1 (10 mg) in DMF (1 mL) and N,N-diisopropylethylamine (10 mg) in DMF (2 mL). Close the cap of the reaction vessel and incubate the solution at 60 °C for 1 h. Cool the resultant solution to room temperature and use it as an HPLC sample.
