Used in the synthesis of pharmaceutical intermediates, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in medicinal chemistry due to its ability to form stable aromatic and heterocyclic frameworks. Commonly employed in cross-coupling reactions to construct biaryl systems found in bioactive molecules. Also utilized in the preparation of ligands for metal-catalyzed reactions, enhancing catalytic efficiency in organic synthesis. Its carboxylic acid functionality allows for easy derivatization into amides, esters, and other functional groups for structure-activity relationship studies.
