Used in organic synthesis as a building block for pharmaceuticals and agrochemicals, particularly in Suzuki-Miyaura cross-coupling reactions to form biaryl compounds. Its boronic acid functionality enables the formation of carbon-carbon bonds, making it valuable in drug discovery for constructing heterocyclic frameworks. Commonly employed in the development of kinase inhibitors and other bioactive molecules due to the prevalence of pyrazole motifs in medicinal chemistry. The hydrochloride salt enhances stability and handling during synthesis.
