Used in the synthesis of labeled compounds for research purposes, particularly in nuclear magnetic resonance (NMR) spectroscopy and mass spectrometry. It serves as a deuterated building block in the development of pharmaceuticals and agrochemicals, enabling the study of metabolic pathways and reaction mechanisms. Its fluorine substitution makes it valuable in positron emission tomography (PET) imaging tracer development. Additionally, it is employed in organic chemistry research to investigate fluorine and deuterium effects on molecular behavior and stability.
