Abstract Derivatization of a C 12 Φ‐methyl ester sulfonic acid by using iodide‐trifluoroacetic anhydride in dimethylformamide in a one‐step reaction yielded derivatized sulfonic thiotrifluoroacetates. The latter have been analyzed by gas chromatography‐mass spectrometry (MS) and liquid chromatography‐MS techniques so that, for the first time, the acid composition and the mono sulfonic acid isomer distribution are shown.
