Applicazioni

4-Bromomethyl-6,7-dimethoxycoumarin was used as fluorescent labeling reagent for the reversed-phase HPLC separation and detection of carboxylic acids. It was also used as derivatization reagent:
  • for quantitation of clofibric, bezafibric and fenofibric acids in liver by liquid chromatography
  • in determination of the concentration of tripeptide glutathione by matrix-assisted laser desorption ionization time-of-flight mass spectrometry
  • for determination of carboxylic acids in chromatographic detection

The fluorescence derivatization of 1-(tetrahydro-2-furanyl)-5-fluorouracil (Ftorafur, FT) with 4-bromomethyl-6,7-dimethoxycoumarin (BrMdmc) with 18-crown-6 as catalyst was utilized for a sensitive and selective liquid chromatographic method to determine the concentration of FT in hair. Hair samples collected from rats, which had received

A reliable and validated reversed-phase high-performance liquid chromatography (HPLC) method using fluorescence detection is reported for the simultaneous quantitation of mycophenolic acid (MPA) and valproic acid (VPA) in human plasma. The method is based on the pre-column derivatization of valproic

Matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS) has been broadly applied to analyze high-molecular-weight compound (such as polymer or proteomic research) but seldom used for low-molecular-weight compound analysis. The objective of this study is the development of a
