Used in organic synthesis as a key intermediate for the preparation of various pharmaceuticals and agrochemicals. It is particularly valuable in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds to create complex molecules. Its deuterated form enhances metabolic stability in drug development, making it useful for studying pharmacokinetics and drug metabolism. Additionally, it serves as a building block in the synthesis of pyrimidine derivatives, which are essential in designing compounds with potential biological activity.
