Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other bioactive molecules. Its structure allows for selective cross-coupling reactions, making it valuable in medicinal chemistry for constructing complex aromatic systems. Commonly employed in Suzuki and Buchwald–Hartwig reactions to introduce aryl or amino groups. Also utilized in the preparation of fluorinated analogs in drug discovery, where the trifluoromethyl group enhances metabolic stability and lipophilicity.
