This compound is primarily used in organic synthesis, particularly in cross-coupling reactions such as the Suzuki-Miyaura reaction. It serves as a key reagent for introducing deuterium-labeled pyridine moieties into complex molecules, which is valuable in the development of pharmaceuticals and agrochemicals. Its deuterated form enhances the stability and metabolic properties of the target compounds, making it useful in drug discovery and development. Additionally, it plays a role in the synthesis of labeled compounds for research in mechanistic studies, isotope effects, and mass spectrometry analysis.
