This compound is primarily used in pharmaceutical research and development, particularly in the synthesis of deuterated drug molecules. The deuterium (D3) substitution enhances metabolic stability, making it valuable for creating compounds with improved pharmacokinetic properties. It is also employed in cross-coupling reactions, such as Suzuki-Miyaura reactions, to construct complex organic molecules, especially in the development of bioactive pyrimidine derivatives. Its boronic acid group facilitates efficient coupling with aryl halides, making it a key intermediate in medicinal chemistry for designing potential therapeutic agents.
