15(S)-HETE-d₈contains eight deuterium atoms at the 5, 6, 8, 9, 11, 12, 14, and 15 positions. It is intended for use as an internal standard for the quantification of 15(S)-HETE by GC-or LC-MS. 15(S)-HETE is a major arachidonic acid metabolite from the 15-lipoxygenase pathway. In mammals, 15(S)-HETE is synthesized in the respiratory epithelium, leukocytes, and reticulocytes.¹15(S)-HETE is present in µg/ml concentrations in the nasal secretions of allergic rhinitis.²
