(±)14(15)-DiHET-d11 contains 11 deuterium atoms at the 16, 16, 17, 17, 18, 18, 19, 19, 20, 20, and 20 positions. It is intended for use as an internal standard for the quantification of (±)14(15)-DiHET by GC- or LC-mass spectrometry. Epoxide hydrolases convert the EETs into vicinal diols, with the concurrent loss of much of their biological activity.1 (±)14(15)-DiHET is the urinary metabolite of (±)14(15)-EET which has been documented by GC-MS to be elevated in pregnancy-induced hypertension.2
