Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of non-steroidal anti-inflammatory drugs (NSAIDs) and other bioactive molecules. Its structure allows for selective functionalization, making it valuable in constructing complex heterocyclic compounds. Commonly employed in organic synthesis to introduce brominated aromatic scaffolds with amide and carboxylic acid functionalities, which are useful in drug discovery and medicinal chemistry research. Also utilized in the preparation of fluorescent probes and dyes due to its ability to undergo coupling reactions and form stable derivatives.
