2‐Naphthalene‐ d 7 ‐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‐ d 8 and sulfuric acid‐ d 2 . A high‐performance liquid chromatographic method was developed to separate 1‐ and 2‐naphthalene‐ d 7 ‐sulfonic acids. The electron impact mass spectrum and isotopic purity of the 2‐naphthalene‐ d 7 ‐sulfonic acid were determined.
