Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of nonsteroidal anti-inflammatory drugs (NSAIDs) and other bioactive molecules. Its structure allows for selective functionalization, making it valuable in constructing complex organic compounds. Commonly employed in cross-coupling reactions and as a building block in medicinal chemistry for introducing aromatic carboxylic acid motifs. Also utilized in the preparation of agrochemicals and specialty polymers due to its reactivity and stability in multi-step syntheses.
