Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions, where the boronate ester group facilitates efficient carbon-carbon bond formation under mild conditions, enabling the synthesis of complex pyrazole derivatives in pharmaceutical and agrochemical research. The 2-bromoethyl substituent provides opportunities for further functionalization, such as nucleophilic substitution or intramolecular cyclization to form small rings, enhancing its utility in constructing diverse biologically active molecules. Commonly employed in the development of kinase inhibitors and other therapeutic agents where pyrazole scaffolds are critical. Also applied in materials science for building functional organic compounds with tailored electronic properties.
