This compound is primarily used in research settings as a stable isotope-labeled internal standard for the quantification of docosahexaenoyl ethanolamide (DHEA) in biological samples. It aids in the accurate measurement of DHEA levels, which is crucial for studying its role in various physiological processes, including neuroprotection, anti-inflammatory effects, and modulation of the endocannabinoid system. Researchers utilize it in mass spectrometry-based assays to ensure precision and reliability in analytical studies. Its application is particularly valuable in understanding the biochemical pathways and therapeutic potential of DHEA in conditions like neurodegenerative diseases, inflammation, and metabolic disorders.
