Used in pharmaceutical research as a deuterated analog for metabolic studies, enabling the tracking of drug pathways and mechanisms with enhanced precision due to its isotopic labeling. It serves as a key intermediate in the synthesis of complex molecules, particularly in the development of targeted therapies. Its incorporation into compounds improves stability and bioavailability, making it valuable in drug discovery and development. Additionally, it is employed in NMR spectroscopy for structural analysis, aiding in the understanding of molecular interactions and conformations.
