This compound is primarily utilized in organic synthesis, particularly in cross-coupling reactions such as Suzuki-Miyaura reactions. It serves as a key reagent for introducing the pyridine moiety into complex molecules, which is valuable in the development of pharmaceuticals and agrochemicals. Its deuterated form enhances its use in mechanistic studies and isotopic labeling, aiding in the tracking of chemical pathways and metabolic processes in research. Additionally, the tert-butyl group provides steric hindrance, which can be advantageous in controlling reaction selectivity and improving the stability of intermediates during synthesis.
