Used primarily as an intermediate in pharmaceutical synthesis, especially in Suzuki-Miyaura cross-coupling reactions. Its pyrazole ring and boronate ester group enable efficient formation of carbon-carbon bonds, making it valuable in constructing complex heterocyclic systems found in bioactive molecules. Commonly employed in the development of kinase inhibitors and other drug candidates where nitrogen-containing heterocycles are key structural elements. The tert-butyl carbamate (Boc) protecting group allows for selective deprotection under mild acidic conditions, facilitating stepwise synthesis in peptide-like frameworks. Suitable for use in medicinal chemistry and R&D settings requiring high-purity boronic ester building blocks.
