Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) for central nervous system agents and anti-inflammatory drugs. Its functional groups enable selective reactions, making it valuable in constructing complex organic molecules. Commonly employed in cross-coupling reactions such as Suzuki and Heck reactions to build biaryl structures found in drug candidates. Also utilized in agrochemical research for designing novel pesticides and herbicides due to its aromatic substitution pattern and reactivity. Its bromo and aldehyde groups allow for sequential derivatization, supporting its role in combinatorial chemistry and high-throughput screening in drug discovery.
