Used as a labeling agent in nuclear magnetic resonance (NMR) spectroscopy, it helps in studying molecular structures and dynamics due to its deuterium substitution. It is also employed in organic synthesis as a building block for creating complex molecules, particularly in pharmaceuticals and agrochemicals. Its stable isotopic labeling makes it valuable in metabolic studies and tracing biochemical pathways. Additionally, it serves as a precursor in the development of ionic liquids, which are used in various industrial applications like catalysis and electrochemistry.
