Used in the synthesis of deuterium-labeled compounds, particularly in pharmaceutical research and development. It serves as a key intermediate in the preparation of isotopically labeled drugs, aiding in metabolic studies and drug discovery. Its deuterium-labeled structure allows for tracking and analysis of drug behavior in biological systems, enhancing the understanding of pharmacokinetics and pharmacodynamics. Additionally, it is employed in the production of agrochemicals and other specialty chemicals where isotopic labeling is required for research or regulatory purposes.
