Used as an intermediate in the synthesis of biologically active compounds, particularly in pharmaceutical research targeting kinase inhibitors and anti-inflammatory agents. Its structure allows for selective modification, making it valuable in developing drug candidates with improved potency and metabolic stability. Commonly employed in cross-coupling reactions due to the trifluoromethylsulfonyl oxy group, enabling carbon–carbon bond formation in complex molecule assembly. Also utilized in the preparation of pyrazole-based derivatives for studies in medicinal chemistry.
