Used as a key reagent in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in organic synthesis. Its boron-containing structure allows it to react with aryl or vinyl halides in the presence of a palladium catalyst, facilitating the construction of biaryl and conjugated systems important in pharmaceuticals, agrochemicals, and advanced materials. The presence of the m-tolyl group makes it valuable for introducing meta-substituted aromatic motifs into larger molecules. Stable and compatible with a variety of functional groups, it is particularly useful in late-stage functionalization during drug development.
