Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions for the synthesis of biaryl compounds in pharmaceutical and agrochemical research. Its boronate ester group enables efficient carbon-carbon bond formation under mild conditions. Commonly employed in the development of functional materials and active pharmaceutical ingredients (APIs) where trifluoromethyl ketone and piperazine motifs are required. Offers good stability and reactivity, making it valuable in medicinal chemistry for constructing complex molecules with enhanced metabolic stability and binding affinity.
