(2-(3-methoxyphenyl)pyrimidin-5-yl)boronic acid is primarily utilized in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions. This reaction is widely employed in the pharmaceutical industry to create complex molecules, including drug candidates, by forming carbon-carbon bonds. The compound serves as a key intermediate in the development of biologically active molecules, such as inhibitors or receptor modulators, due to its boronic acid group, which facilitates coupling with aryl halides. Additionally, it is used in material science for the synthesis of organic electronic materials, where precise molecular structures are required. Its role in these applications highlights its importance in advancing both medicinal chemistry and functional materials research.
