Used as a labeled compound in chemical research, particularly in studies involving isotopic labeling to trace reaction mechanisms or metabolic pathways. It serves as a building block in the synthesis of more complex molecules, especially in pharmaceuticals, where deuterium-labeled compounds are valuable for drug development and testing. Its application extends to analytical chemistry, where it aids in the development of methods for detecting and quantifying substances using mass spectrometry or NMR spectroscopy. Additionally, it can be employed in material science for the creation of specialized polymers or organic materials with unique properties.
