Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of bioactive molecules with antifungal, antibacterial, or anti-inflammatory properties. Its aldehyde and bromo functional groups allow for versatile chemical modifications, making it valuable in constructing complex organic compounds. Commonly employed in cross-coupling reactions such as Suzuki or Heck reactions to build biaryl systems found in drug candidates. Also utilized in the preparation of natural product analogs and heterocyclic compounds for medicinal chemistry research.
