Used in pharmaceutical research as a labeled compound for tracing and studying metabolic pathways due to its deuterium atoms, which provide a distinct isotopic signature. It serves as a key intermediate in the synthesis of deuterated drugs, enhancing the understanding of drug behavior and stability. Additionally, it is employed in the development of active pharmaceutical ingredients (APIs) where isotopic labeling is crucial for pharmacokinetic and pharmacodynamic studies. Its application extends to nuclear magnetic resonance (NMR) spectroscopy, aiding in structural analysis and molecular characterization.
