Used in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions, to construct carbon-carbon bonds for pharmaceuticals and agrochemicals. Its boronic acid group enables efficient coupling with aryl or vinyl halides under palladium catalysis. Commonly applied in the development of active ingredients in crop protection agents and medicinal compounds where pyrimidine derivatives are needed. Also utilized in research for creating libraries of heterocyclic compounds in drug discovery. Stable and selective under various reaction conditions, making it suitable for late-stage functionalization in complex molecule synthesis.
