Glutathione alkylester isotopologue and method for detecting reactive metabolite

Abstract

[Problem] To provide a novel isotope-labeled compound that can be used as a trapping agent and that is useful for picking out drug-candidate compounds that produce reactive metabolites. [Solution] Provided is a glutathione alkylester isotopologue represented by general formula (1). In formula (1), R1 represents a linear or branched alkoxy group in which at least one of carbon, oxygen, and hydrogen atoms contained therein is isotope-labeled and which has 1 to 8 carbon atoms or a cycloalkoxy group in which at least one of carbon, oxygen, and hydrogen atoms contained therein is isotope-labeled and which has 3 to 8 carbon atoms.
