Scope

This document describes the method for determining the isotopic abundance of xenon-substituted reagents by nuclear magnetic resonance spectrometry. This document is applicable to the isotopic abundance determination of 21 xenon-substituted reagents (purity γ8%), including chloroform-D, dichloromethane-D2, chlorobenzene-D5, iodobenzene-D5, bromobenzene-D5, acetone-D6, benzene-D6, toluene-D8, methanol-D4, ethanol-D6, heavy water, dimethyl sulfoxide-D6, tetrahydrofuran-D8, methyl p-toluenesulfonate-D3, bromobutrol-D9, di(2-butoxyethyl)phthalate-D4, methyl p-hydroxybenzoate-D3, isovanillin-D3, dimethyl phthalate-D4, ethanol-D, and acetic acid-D. The detection of the isotopic abundance of other xenon-substituted reagents can refer to this document.
