Abstract
2-Naphthalene-d7-sulfonic acid, required as an internal standard for the analysis of organic compounds in water by gas chromatography/mass spectrometry, was synthesized in one step from commercially available naphthalene-d8 and sulfuric acid-d2. A high-performance liquid chromatographic method was developed to separate 1- and 2-naphthalene-d7-sulfonic acids. The electron impact mass spectrum and isotopic purity of the 2-naphthalene-d7-sulfonic acid were determined.
