Overview
8(S)-HETE (CAS 105500-09-2 ), also referenced in research contexts as 8(R)-HETE when specifying stereoisomeric counterparts, is a hydroxyeicosatetraenoic acid produced endogenously.
It is formed through lipoxygenase-mediated oxidation of arachidonic acid. It functions as a bioactive lipid mediator used primarily as a reference standard and research reagent in eicosanoid biology.
In pharmaceutical research, it is used as an analytical reference standard for quantifying hydroxy-fatty acid profiles in biological samples. This supports drug discovery programs targeting lipid signaling pathways.
Biotechnology laboratories employ it in receptor binding assays and enzyme activity studies focused on lipoxygenase and cytochrome P450 pathways. It is also used in cell-based assays investigating signaling.
Precise stereochemical identity is critical for reproducible results in these studies. Metabolomics and lipidomics platforms use it as a certified reference material for method validation and calibration.
The product is supplied as a solution, typically in ethanol or a compatible organic solvent, given its instability in neat form. Standard pack sizes are small-scale, ranging from microgram to low-milligram quantities.
Material is generally available at research-grade purity with a certificate of analysis confirming stereochemical identity and concentration. It meets rigorous internal quality standards for analytical consistency.
