Used in Suzuki-Miyaura cross-coupling reactions as a boron reagent for constructing carbon-carbon bonds in pharmaceutical and agrochemical synthesis. Its pyrrolopyridine scaffold is valuable for developing bioactive molecules, particularly kinase inhibitors. The boronic ester group enables efficient coupling with aryl halides under mild conditions, making it useful in late-stage functionalization during drug discovery. Stable and compatible with various functional groups, it supports the rapid assembly of complex heterocyclic compounds.
