Widely used in Suzuki-Miyaura cross-coupling reactions, this compound serves as a key boronic ester reagent for forming carbon-carbon bonds in organic synthesis. Its stability and reactivity make it valuable for constructing biaryl and heterobiaryl structures, commonly found in pharmaceuticals, agrochemicals, and functional materials. The presence of the chloro and methyl substituents allows for selective transformations, enabling fine-tuning of molecular architecture in drug discovery and development processes. It is particularly useful in late-stage functionalization due to its compatibility with various functional groups under palladium catalysis.
