Used in Suzuki-Miyaura cross-coupling reactions to synthesize complex pyrazole derivatives, which are key scaffolds in pharmaceuticals and agrochemicals. The Boc-protected pyrazole ring provides stability and selectivity during coupling, while the boronic acid group enables efficient carbon-carbon bond formation. Commonly applied in drug discovery for building bioactive molecules, especially kinase inhibitors and anti-inflammatory agents. Its protected form allows for later deprotection and further functionalization in multi-step synthesis.
