Used in the synthesis of deuterated organic compounds, particularly in pharmaceutical research where deuterium labeling is essential for studying drug metabolism and pharmacokinetics. It serves as a key intermediate in the production of deuterated aromatic amines, which are valuable in NMR spectroscopy for structural analysis and in the development of deuterated drugs to enhance stability and reduce side effects. Additionally, it is employed in material science for creating specialized polymers and coatings with improved properties.
