Used in the synthesis of deuterated compounds for research purposes, particularly in the study of metabolic pathways and drug metabolism. It serves as a labeled analog in mass spectrometry and NMR spectroscopy, aiding in the precise tracking of chemical reactions and molecular interactions. Its incorporation into pharmaceuticals helps in understanding the pharmacokinetics and distribution of drugs within biological systems. Additionally, it is employed in the development of diagnostic agents and in the investigation of enzyme mechanisms due to its stable isotopic labeling.
