Used primarily as a stable isotope-labeled internal standard in mass spectrometry and nuclear magnetic resonance (NMR) studies. Its deuterated structure allows for precise tracking and quantification of metabolic pathways in biochemical research, especially in studies involving fatty acid metabolism. The compound aids in distinguishing between endogenous and exogenous analytes due to its altered mass while maintaining nearly identical chemical behavior to the non-labeled analog. Commonly applied in pharmaceutical development, metabolic profiling, and tracer experiments where high analytical accuracy is required.
