Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of receptor antagonists and enzyme inhibitors. Its structure supports the formation of bioactive molecules, making it valuable in medicinal chemistry for drug discovery. Commonly employed in cross-coupling reactions such as Suzuki-Miyaura to build complex heterocyclic systems. Also utilized in the preparation of functional materials where aromatic and heteroaromatic carboxylic acids are required for molecular design.
