Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in pharmaceutical and agrochemical synthesis. This deuterated analog (98 atom % D at the methyl group) is particularly valuable for isotopic labeling in mechanistic studies, NMR spectroscopy, and pharmacokinetic investigations in drug discovery. Its boronate ester group facilitates efficient coupling with aryl or heteroaryl halides under palladium catalysis, making it valuable in the development of complex organic molecules, particularly in drug discovery and materials science. The deuterated methyl and pyrazole moieties contribute to structural diversity, bioactivity, and isotopic tracking in final compounds.
