Used as a labeled compound in research and development, particularly in the field of organic chemistry and pharmacology. It serves as a deuterated analog in studies involving isotopic labeling to track and analyze chemical reactions, metabolic pathways, and drug mechanisms. Its incorporation helps in understanding reaction kinetics and the behavior of molecules in biological systems. Additionally, it is employed in the synthesis of complex organic molecules where deuterium labeling is required for spectroscopic studies, such as NMR or mass spectrometry, to gain detailed insights into molecular structures and interactions.
