Used as a labeled compound in research and analytical chemistry, particularly in NMR spectroscopy and mass spectrometry, to study reaction mechanisms and metabolic pathways. It serves as a stable isotope-labeled internal standard for accurate quantification in complex biological and environmental samples. Its deuterated structure makes it valuable for tracing and identifying specific compounds in isotopic labeling experiments. Additionally, it aids in the development of pharmaceuticals by providing insights into drug metabolism and degradation processes.
