SYNTHESIS OF DEUTERIUM LABELLED METHYL CHLOROFORMATE

Abstract

Most analytical methods in metabolomics allow determination of relative intensities or require several internal standards of metabolites. For quantitative analysis, determination of absolute concentrations is required. For this purpose, the gas chromatography/tandem mass spectrometry methods are used, based on methyl chloroformate derivatization and quantification by spiking samples with metabolite standards separately derivatized with deuterated derivatization reagents. Described herein is the synthesis of deuterated methyl chloroformate – the reagent for absolute quantitative metabolite analysis by gas chromatography-mass spectrometry. The method allows preparation and isolation of deuteromethylchloroformate with high yields.
