Used as a deuterated reagent in organic synthesis, particularly in the preparation of labeled compounds for research and development. It serves as a building block in the synthesis of deuterated pharmaceuticals, aiding in drug metabolism studies and pharmacokinetic research. Its incorporation into molecules helps in tracing and analyzing chemical pathways using techniques like NMR and mass spectrometry. Additionally, it is employed in the development of advanced materials and polymers where isotopic labeling is required for structural analysis.
