Descripción

Application

This analytical standard was used as follows:

• Determination of _L- and _D-amino acids and glycine by liquid chromatography-tandem mass spectrometry (LC-MS/MS) following their derivatization with chiral Marfey’s reagent
• High-performance liquid chromatography (HPLC) based amino acid analysis during the characterization of defatted rice bran (DRB) protein concentrate to evaluate its iron binding ability
• Development of a gas chromatography-mass spectrometry (GC-MS) procedure for the profiling of 112 amino-carboxylic metabolites in human urine samples using 1,1,1,2,2,3,3-heptafluorobutyl chloroformate for derivatization and liquid-liquid microextraction for sample treatment
• Non-enantiomeric detection and quantification of amino acids in their various forms— free, dissolved, particulate, and total, in natural water samples by HPLC coupled with fluorescence detection using a C₁₈ column
