A gas-liquid chromatographic assay has been developed to measure isethionic acid after methylation with diazomethane. The identity of the products of methylation has been confirmed by mass-spectrometry and nuclear magnetic resonance spectroscopy. The method was used to measure isethionic acid in rat heart, dog heart and rat brain. The assay was validated by measuring isethionic acid on squid axoplasm. We have been able to detect only trace amounts of isethionic acid in rat brain (0.2 mg/100g) and rat heart (0.1 mg/ 100g). None was found in dog heart.
