(2-(m-tolyl)pyrimidin-5-yl)boronic acid is widely used in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions. This reaction is essential for creating carbon-carbon bonds, enabling the synthesis of complex organic molecules, including pharmaceuticals, agrochemicals, and advanced materials. Its boronic acid group facilitates the coupling with aryl or vinyl halides, making it a valuable building block in medicinal chemistry for drug discovery and development. Additionally, it is employed in the preparation of heterocyclic compounds, which are crucial in designing biologically active molecules. Its stability and reactivity also make it suitable for use in material science, particularly in the development of organic electronic components.
