Product Overview
Description:
12-epi Leukotriene B4-d4 is a tetradeuterated stable isotope internal standard featuring four strategically integrated deuterium atoms, designed for precise calibration in chromatography-mass spectrometry assays. The matching native analyte represents the unnatural 12(S) epimer of leukotriene B4, serving as a vital stereospecific reference tracer to differentiate enzymatic eicosanoid pathways from non-enzymatic lipid hydrolysis events.
Labeling:
Stable isotope-labeled
Synonyms:
5S,12S-dihydroxy-6Z,8E,10E,14Z-eicosatetraenoic-6,7,14,15-d4 acid; 12-epi LTB4-d4
Formula:
C20H28D4O4
