Used as a deuterated reagent in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions, to introduce boronic acid groups into molecules. Its deuterated form aids in isotopic labeling studies, enabling tracking and analysis of reaction mechanisms and metabolic pathways. Commonly applied in pharmaceutical research for developing deuterated drug candidates, which can enhance metabolic stability and bioavailability. Also utilized in material science for creating advanced polymers and functional materials.
